Excellent video I thought I might need a vacuum pump, so rang local Mazda dealers. Some want over £300, but EMG Boston and Donalds of Peterborough will sell one for £120.

I think the dealers are supplied with a vacuum pump kit (which also includes gaskets 'o rings' etc at a reduced price.

First of all, thank you for the fantastic content. Shame I live in England, otherwise, i would have left my Mazda in your garage. Anyways, I still get the p0101 fault code even though I changed all the sensors you mentioned (and the vacuum pump). The SCBC error comes up when engine braking i.e. when coming off motorway. I've not looked at the camshaft yet, and it seems this will be my next move. Fingers crossed it would solve the problem.
Thx a lot for sharing! I also have p0101 error and I get invalid data for the remaining tests.. I took it to the mechanic and he cleared the code but I still get the SCBS forward malfunction and track control symbols on my dashboard. The car actually drives very well, it's only when I am slowing down when exiting motorway that I see the SCBS pops up on the dashboard
The intake manifold blocking & exhaust camshaft / hydraulic tappets are the most likely cause of your problem but it would be worth looking at the exhaust pressure sensor ‘A’ also. The sensors fail & the adjoining pipe blocks causing problems on deAcceleration. I’ll copy and paste a video for you to look at 😉👍👍
The intake manifold blocking is very common, just be careful quite a few commenters are getting caught by not making sure the valves are closed when cleaning & then having an awful job to start it afterwards 🤞👍👍
I also had p0101 and p258B. mazda 6 2015 AWD. I cleaned the entire intake manifold and replaced the vacuum pump, but when the engine warmed up and I depressed the brake pedal p0101 and scbs returned. Then I went to a mazda service and they rewrote the new operating system to the computer, now after about 150km the error did not return. They said if there was another mistake it would be necessary to replace the battery because it no longer meets the parameters, it is still original about 7 years old.

@@kennedysgarage3281 Simmilar fixed in my Mazda Cx5, 2.2Dti 110kw. After replacing vacump pump and cleaning intake manifold dealer fix errors using: " procedure after cleaning intake manifold " . Procedure cost 60Eur. Not sure what they did. Anyway engine works fine.
Very interesting video. Thank you for your great work and tenacity until reaching a final diagnosis. I have same error codes as you and I suspect of same issue. However, the official dealer says that issue is caused by carbon buildup and the solution is to change MAP sensor, clean egr, decarbon engine and change multiple gaskets. Would you be so kind to share TSB you showed in the video? It could be useful to try persuading dealer to check vacuum pump first before trying other thing that could be more expensive. Thanks a lot.
An intake system decarb is the most common starting point. But can generally be proven if needed or not by removing the air intake pipe from throttle body on the intake manifold & the Map sensor to examine both. I have a good video on diagnosing vacuum pump failure too. Just using a scantool, I’ll copy and paste it. It might help 🤞🤞
@@Dermo37 It could cost between €2500 & €3000 if you had to do everything from oil pick up to camshaft & follower’s. People look at it in many different ways, some equate it to the value of the vehicle. Others use value over time ( 3k for 3 or 4 years driving 🤔) It depends on circumstances I guess
@@kennedysgarage3281 there is 187000 miles on my 6 if I spent 3 grand on it the car is only worth a bit more than that next thing turbo's go steering rack . I have already replaced gear box and clutch , dpf problems and throttle bodies replaced
Really a great job! I enjoyed all the 3 parts. Did you notice the faulty codes to come back again after you replaced the vacuum pump? I’m having the same code p0101 on my mazda cx-5. The official mazda mechanic told me that is the maf sensor simply connecting the computer but I don’t trust him. Is there a way to check if the intake manifold/camshaft are dirty or ruined without opening the engine? Best 😊
Hi Daniel, I have come across this P0101 fault 100’s of times now. You have to start by cleaning the intake manifold if you don’t have any knowledge of it being done prior. But it can be proved by removing the MAP sensor & air intake pipe at the throttle body, then looking in with a borascope. If your car has more than 120,000kms or 80,000mls it will need a camshaft kit. It can be proven but only after disassembling the injectors & rocker cover. Also clean the MAP sensor when it’s out, this will definitely fix your car 100%
There was no real noticeable change on them but I believe it was a turbo control related issue. ie when the engine ECU expected a certain amount of air due to a certain turbo position it was out of whack due to the turbo not being in the correct position. If that makes sense 🤔 I’m glad you like the content 😉👍
@@kennedysgarage3281 Your spot on, that makes sense. Looking forward to your next cartoon! P.S when can we expect DiagnosePeter TSB to hit Irish shores 😃
Hello again i hope this p0101 is fixed in your case, but just to let you know i was having problem with my car p258b for vacuum pump also p0101 error, I have changed the vacuum pump and i can confirm same day p0101 error has come back after i drove the car around 80 miles 65 miles one side on the way back drove around 15-20 miles and lights came back on with p0101 code, To create the code drive in 4th gear for 10 15 mints when engine is warm, and take it to around 70 mph keep driving for 10 mints and take foot of the gas pedal and boom lights come back on, :D Good luck hope its sorted for you though 👍
@@kennedysgarage3281 nope, just the vacuum pump i have changed for p258b i also changed exhaust pressure sensor 1 for p0472 code, also getting p0101 code, Hope its sorted for you as you have also replaced camshaft it may be a contrast as you mentioned in the video, Good luck 👍
Great job. Thank you for sharing. I have similar issues on my Mazda 2016, CX5 2.2 dti. Errors occurs after depressing accelerator at 90-100km/h. I replaced vacuum pump, cleaned intake manifold. Nothing changes. What is the engine type and size ? Did you replaced gasket?
@@asd8484Yes. No more errors. Engine runs smoothly. 1.Clean intake manifold from carbon deposits inside manifold, and EGR. 2. Deliver to Mazda dealer for "procedure after manifold cleaning" (probably dealer updates software.) This procedure helps me and my friend.
Hello mate, I just receive P0101 after changing the camshaft, MAF and cleaning MAP and the entity system, will try the vacuum pump, hopefully it resolve it, cuz it’s really annoying…
I have hit this problem before. Have you looked at the exhaust pressure sensor & pipe to it that blocks?? Also do an Airflow meter reset & egr initialisation??? I have also seen hydraulic tappets under the exhaust rockers to fail (get soft) & wear, this issue caught me like you after I had fitted a new camshaft kit 😱😱
Hi Peter would you recommend one of these Mazda engines for use as a taxi? Thinking of buying one and doing egr/dpf delete. What kind of high mileage would they be capable of ? Thanks
I would recommend one ( some people would say I’m mad ) but I wouldn’t delete the egr and Dpf, I don’t find Dpf or egr gives to much trouble. Make sure the injector seals have been replaced & the oil pick up in the sump. Change the oil regularly and I believe that’s it. Neglect causes havoc on this engine 🤔
@@Amay12675 yes. It would stop the intake manifold & ports from getting blocked. But that wouldn’t reduce the likelihood of the engine failing, this happens due to injector seals/washers failing and compression/exhaust gas getting into the crankcase & clogging up oil feeds & jet’s over the exh camshaft. This only my opinion 🤔
Hi Peter i had a 2015 mazda 6 2.2 in last week. Needed a vacuum pump and camshaft no big deal as i havd done a good few already but after doing this one the code p0101 Air flow fault came back with an engine management light. Just curious to see have you seen this before
I have encountered this once or twice and I’m struggling with one at present. I done a software update today after discussing it with MrNiceGuy (he’s on UA-cam too) Ask me in a week or so again and I’ll let you know if it works 😉
Hi Peter, I could do with your help. I'm getting the P0101 (only) code with the CEL, the cars symptom is on mid-full acceleration, there is a flat spot and judder/misfire between 2.5rpm to 3k+rpm. Any ideas what to focus or look towards? The car is a 2016 Mazda6 2.2 diesel Manual Thanks in advance
P0101 is air flow related, so I would start with the most common cause which is the intake manifold and port’s getting blocked with carbon. Also make sure the manifold absolute pressure sensor is clean. After that you could be focusing on injector washers/ seal’s & exhaust camshaft being worn. I have videos on all of these repairs to help you carry out the work if needed 🙏🙏👍
Bad injector seals allows carbon to build up in the crankcase/oil system. Which in turn blocks the oil spray jets over the exhaust camshaft, which wears the camshaft. A worn camshaft doesn’t open the exhaust valves enough, this effect the air quantity entering the engine (P0101). Then the metal shavings from camshaft damage the vacuum pump 🤔 Does this help?
Yes absolutely correct, if the vacuum pump is very bad you will definitely get a P258B brake booster pressure sensor fault. But in my case the vacuum pump wasn’t too bad and the brake booster pressure sensor didn’t see a fault but the turbo control system didn’t have enough vacuum to operate correctly. I’ll put in a link for another video to watch on diagnosing a vacuum pump 👍👍
Hello mate. Great informative content. But there is one more issue. I changed my exhaust camshaft, chsngef oil strainer, cleaned inlet maniforld, replaced MAF sensor, replaced the vaacum pump but i still get this error. P0101 😂 also when it happens it does hapen when applying the brakes not when accelerating and it goes in limp mode. What now boss? 😂
Did you check your exhaust pressure sensor pipe and intake manifold pressure sensor? There could be a software update available too. The fault conditions for this fault to set are fairly specific. The accelerator pedal position needs to be zero and it needs to see the fault for 5 seconds iirc before it logs the fault. It also needs to see the same fault twice on two separate ignition cycles before it brings the mil on. The abs, city brake etc lights can come on first when the first P0101 fault is logged. Egr flow shows as zero for both egr cooler bypass and egr when the vehicle is on overrun in the condition to set the code. The code won’t log if there is a passive regeneration taking place ( which with this fault occurring can cause the dpf to block quicker as it in itself will prevent regeneration taking place once the eml is ill7minated.

Thank you for the information. I do have one more issue with it that I found: On the live data when the car was idling, most of the data was within parameters except one, which was over the limit. The "Turbocharger Compressor Inlet Pressure Sensor A" which, according to the tester the range should be between 0 and 100 kPa, on idle it was sitting at 104 kPa, so red colour. When hard accelerating on the motorway, it was going to 200+ kPa
@@Telorayou the last reply was a fantastic & well explained response 💪💪 That intake pressure sensor A normally sits at 96kpa at idle. Just under atmosphere pressure, due to the turbo changeover flap being closed under 2000rpm. It then jumps up to around 200kpa or so once the engine speed goes over 2000rpm and the trap door opens for the larger low pressure turbo. The only time I have ever been caught with the P0101 is with hydraulic tappets getting soft and not opening the intake & exhaust valves on time 🤔🤔
the car runs well until, sometimes, when I release the accelerator pedal, it enters emergency mode and the error is p0101. after restarting the engine is fine.I also notice that it only seems to come on when I press hard on the accelerator and then when I take off the gas and the revs drop is when it comes on
@@avtofavoritby2138 the problem starts when the injector seals start leaking, carbon gets into the oil which blocks the jets that spray oil onto the exhaust camshaft. This in turn causes the camshaft to wear & then the steel from the camshaft gets into the oil which damages the vacuum pump. Does that make sense?
@@kennedysgarage3281 Does replacing the pump fix the problem? you need to deal with the injectors, then with the camshaft and only then with the vacuum pump, right??
@@avtofavoritby2138 replacing the vacuum pump alone does not fix the problem. First I would suggest removing the injectors just to examine the copper washers underneath, it only takes around 1 hour . Move forward from there 🤔
Hi Peter , I ❤ your channel, but wouldn"t you agree that Mazda should STOP producing these crappy 2.2L diesel engines ? They are a total disaster, the excessive carbon buildup, the exhaust camshaft wearing out, and EVERYTHING becomes plugged up with carbon deposits ! I would NEVER, EVER get a Mazda with that Diesel engine ! "Skyactive Technology " my ass !!
😂😂😂😂 They are quite a few items that fail very regularly on these engines alright. They have revised the engine design from around 2017 on, they seem to be quite a bit better 🤞🤞 For me a lot of owners & garages alike are getting stuck on repairing them. And we are getting very familiar with them and every repair on them is getting faster & easier.

@@kennedysgarage3281 Simmilar fixed in my Mazda Cx5, 2.2Dti 110kw. After replacing vacump pump and cleaning intake manifold dealer fix errors using: " procedure after cleaning intake manifold " . Procedure cost 60Eur. Not sure what they did. Anyway engine works fine.
@@mindaugasb6962 good information thanks for sharing 😉👍
Very interesting video. Thank you for your great work and tenacity until reaching a final diagnosis. I have same error codes as you and I suspect of same issue. However, the official dealer says that issue is caused by carbon buildup and the solution is to change MAP sensor, clean egr, decarbon engine and change multiple gaskets. Would you be so kind to share TSB you showed in the video? It could be useful to try persuading dealer to check vacuum pump first before trying other thing that could be more expensive. Thanks a lot.
An intake system decarb is the most common starting point. But can generally be proven if needed or not by removing the air intake pipe from throttle body on the intake manifold & the Map sensor to examine both. I have a good video on diagnosing vacuum pump failure too. Just using a scantool, I’ll copy and paste it. It might help 🤞🤞

Great video Peter. I have all the above issues with my Mazda 6. Probably the worse car I have ever bought. Fix 1 problem and another arrives
😂😂, not many good cars on the road nowadays 🤔👍
Wot was the ball park for all that work to be done Peter roughly. Is it viable to carry out that much work
@@Dermo37 It could cost between €2500 & €3000 if you had to do everything from oil pick up to camshaft & follower’s. People look at it in many different ways, some equate it to the value of the vehicle. Others use value over time ( 3k for 3 or 4 years driving 🤔)
It depends on circumstances I guess
@@kennedysgarage3281 there is 187000 miles on my 6 if I spent 3 grand on it the car is only worth a bit more than that next thing turbo's go steering rack . I have already replaced gear box and clutch , dpf problems and throttle bodies replaced
@@Dermo37 what is actually happening to your car now ??
All of the above may not be needed 🤔
Really a great job! I enjoyed all the 3 parts.
Did you notice the faulty codes to come back again after you replaced the vacuum pump?
I’m having the same code p0101 on my mazda cx-5.
The official mazda mechanic told me that is the maf sensor simply connecting the computer but I don’t trust him. Is there a way to check if the intake manifold/camshaft are dirty or ruined without opening the engine?
Best 😊
Hi Daniel, I have come across this P0101 fault 100’s of times now. You have to start by cleaning the intake manifold if you don’t have any knowledge of it being done prior. But it can be proved by removing the MAP sensor & air intake pipe at the throttle body, then looking in with a borascope.
If your car has more than 120,000kms or 80,000mls it will need a camshaft kit. It can be proven but only after disassembling the injectors & rocker cover. Also clean the MAP sensor when it’s out, this will definitely fix your car 100%
great job Peter
I’ll call it a great job in around 3 weeks when the owner tells me it flying 🤞🤞
Thanks for watching Dave 🙏🙏
Well done Peter, loving your content. What were the MAP and MAF readings after fitting the new vacuum pump?
There was no real noticeable change on them but I believe it was a turbo control related issue. ie when the engine ECU expected a certain amount of air due to a certain turbo position it was out of whack due to the turbo not being in the correct position. If that makes sense 🤔
I’m glad you like the content 😉👍
@@kennedysgarage3281 Your spot on, that makes sense. Looking forward to your next cartoon!
P.S when can we expect DiagnosePeter TSB to hit Irish shores 😃
Hello again i hope this p0101 is fixed in your case, but just to let you know i was having problem with my car p258b for vacuum pump also p0101 error,
I have changed the vacuum pump and i can confirm same day p0101 error has come back after i drove the car around 80 miles
65 miles one side on the way back drove around 15-20 miles and lights came back on with p0101 code,
To create the code drive in 4th gear for 10 15 mints when engine is warm, and take it to around 70 mph keep driving for 10 mints and take foot of the gas pedal and boom lights come back on, :D
Good luck hope its sorted for you though 👍
Did you have to change the exhaust camshaft & rockers???
@@kennedysgarage3281 nope, just the vacuum pump i have changed for p258b i also changed exhaust pressure sensor 1 for p0472 code, also getting p0101 code,
Hope its sorted for you as you have also replaced camshaft it may be a contrast as you mentioned in the video,
Good luck 👍
@@nmalik88 I’d say you have a camshaft failure which caused the vacuum pump to fail 🤔🤔
Driving my one for another 100 kms today and all still good 🤞🤞
Hey @nmalik88 did you manage to fix the issue after all?
I have similar problem as you explain here, only I get codes P0101 and U0442(00)
Just had this problem show up at under 50k miles on my 6. Have had it dealer serviced since having the car from Mazda fleet. Really annoying fault.
Intake manifold blocked with carbon or exhaust camshaft & hydraulic tappets are the most likely cause of you issue 🤔🤔
Great job. Thank you for sharing. I have similar issues on my Mazda 2016, CX5 2.2 dti. Errors occurs after depressing accelerator at 90-100km/h. I replaced vacuum pump, cleaned intake manifold. Nothing changes. What is the engine type and size ? Did you replaced gasket?
Did you replace the exhaust camshaft ??
@@kennedysgarage3281 No yet. Mazda dealer suggested to clean manifold only. I'll plan to change it.
Hello , have same car as YOU..same year..and same problem..u found the solution ? 😩😭
@@asd8484Yes. No more errors. Engine runs smoothly.
1.Clean intake manifold from carbon deposits inside manifold, and EGR.
2. Deliver to Mazda dealer for "procedure after manifold cleaning" (probably dealer updates software.)
This procedure helps me and my friend.

Was the vacuum pump the fix in the end
Hello mate, I just receive P0101 after changing the camshaft, MAF and cleaning MAP and the entity system, will try the vacuum pump, hopefully it resolve it, cuz it’s really annoying…
I have hit this problem before. Have you looked at the exhaust pressure sensor & pipe to it that blocks??
Also do an Airflow meter reset & egr initialisation???
I have also seen hydraulic tappets under the exhaust rockers to fail (get soft) & wear, this issue caught me like you after I had fitted a new camshaft kit 😱😱
@@kennedysgarage3281 I have not, but will schedule a meeting with my mechanic next couple of weeks and will run a full diagnostic
Hi Peter would you recommend one of these Mazda engines for use as a taxi? Thinking of buying one and doing egr/dpf delete. What kind of high mileage would they be capable of ? Thanks
I would recommend one ( some people would say I’m mad ) but I wouldn’t delete the egr and Dpf, I don’t find Dpf or egr gives to much trouble.
Make sure the injector seals have been replaced & the oil pick up in the sump. Change the oil regularly and I believe that’s it.
Neglect causes havoc on this engine 🤔
@@kennedysgarage3281 would egr/dpf delete not aid to a cleaner engine and less carbon build up inside??
@@Amay12675 yes. It would stop the intake manifold & ports from getting blocked. But that wouldn’t reduce the likelihood of the engine failing, this happens due to injector seals/washers failing and compression/exhaust gas getting into the crankcase & clogging up oil feeds & jet’s over the exh camshaft.
This only my opinion 🤔
Have you tried using forscan as the scan tool to see if it give you the same values for air flow?
No, I unfortunately don’t have forscan ☹️
Hi Peter i had a 2015 mazda 6 2.2 in last week. Needed a vacuum pump and camshaft no big deal as i havd done a good few already but after doing this one the code p0101 Air flow fault came back with an engine management light. Just curious to see have you seen this before
I have encountered this once or twice and I’m struggling with one at present. I done a software update today after discussing it with MrNiceGuy (he’s on UA-cam too)
Ask me in a week or so again and I’ll let you know if it works 😉
I thought at first maybe dpf was blocked but all readings seem fine. @@kennedysgarage3281
Hi Peter, I could do with your help. I'm getting the P0101 (only) code with the CEL, the cars symptom is on mid-full acceleration, there is a flat spot and judder/misfire between 2.5rpm to 3k+rpm. Any ideas what to focus or look towards?
The car is a 2016 Mazda6 2.2 diesel Manual
Thanks in advance
P0101 is air flow related, so I would start with the most common cause which is the intake manifold and port’s getting blocked with carbon. Also make sure the manifold absolute pressure sensor is clean.
After that you could be focusing on injector washers/ seal’s & exhaust camshaft being worn. I have videos on all of these repairs to help you carry out the work if needed 🙏🙏👍
Where did you get the part from please?
Every days a school day 👍 jobs a gooden.
Fingers crossed John 🤞, but she is still flying at this point in time 😉
Hi does bad injector seals delute oil which damage cams then it whacks vac pump..? How come bad vac pump causes MAF P0101 codes..?
Bad injector seals allows carbon to build up in the crankcase/oil system. Which in turn blocks the oil spray jets over the exhaust camshaft, which wears the camshaft. A worn camshaft doesn’t open the exhaust valves enough, this effect the air quantity entering the engine (P0101).
Then the metal shavings from camshaft damage the vacuum pump 🤔
Does this help?
I've changed vacuum pump and still have the same problem.
What exactly is your issue with the car ??
In the previous video about the vacuum pump, you performed a test with a diagnostic computer. Shouldn't a damaged vacuum pump give a P258B error?
Yes absolutely correct, if the vacuum pump is very bad you will definitely get a P258B brake booster pressure sensor fault. But in my case the vacuum pump wasn’t too bad and the brake booster pressure sensor didn’t see a fault but the turbo control system didn’t have enough vacuum to operate correctly. I’ll put in a link for another video to watch on diagnosing a vacuum pump 👍👍

Hello mate. Great informative content. But there is one more issue. I changed my exhaust camshaft, chsngef oil strainer, cleaned inlet maniforld, replaced MAF sensor, replaced the vaacum pump but i still get this error. P0101 😂 also when it happens it does hapen when applying the brakes not when accelerating and it goes in limp mode. What now boss? 😂
Did you check your exhaust pressure sensor pipe and intake manifold pressure sensor? There could be a software update available too. The fault conditions for this fault to set are fairly specific. The accelerator pedal position needs to be zero and it needs to see the fault for 5 seconds iirc before it logs the fault. It also needs to see the same fault twice on two separate ignition cycles before it brings the mil on. The abs, city brake etc lights can come on first when the first P0101 fault is logged. Egr flow shows as zero for both egr cooler bypass and egr when the vehicle is on overrun in the condition to set the code. The code won’t log if there is a passive regeneration taking place ( which with this fault occurring can cause the dpf to block quicker as it in itself will prevent regeneration taking place once the eml is ill7minated.
This is the fault description and setting criteria for a CX5

Thank you for the information. I do have one more issue with it that I found: On the live data when the car was idling, most of the data was within parameters except one, which was over the limit. The "Turbocharger Compressor Inlet Pressure Sensor A" which, according to the tester the range should be between 0 and 100 kPa, on idle it was sitting at 104 kPa, so red colour. When hard accelerating on the motorway, it was going to 200+ kPa
@@Telorayou the last reply was a fantastic & well explained response 💪💪
That intake pressure sensor A normally sits at 96kpa at idle. Just under atmosphere pressure, due to the turbo changeover flap being closed under 2000rpm. It then jumps up to around 200kpa or so once the engine speed goes over 2000rpm and the trap door opens for the larger low pressure turbo.
The only time I have ever been caught with the P0101 is with hydraulic tappets getting soft and not opening the intake & exhaust valves on time 🤔🤔
hello mechanic. Did the car get better after everything changed. Mine makes the same mistake. I want to know what to do with it. thanks
What is actually happening to your car ???
Any fault codes stored??
the car runs well until, sometimes, when I release the accelerator pedal, it enters emergency mode and the error is p0101. after restarting the engine is fine.I also notice that it only seems to come on when I press hard on the accelerator and then when I take off the gas and the revs drop is when it comes on

@@kennedysgarage3281please answer the problem is in the vacuum pump or in the camshaft
@@avtofavoritby2138 the problem starts when the injector seals start leaking, carbon gets into the oil which blocks the jets that spray oil onto the exhaust camshaft. This in turn causes the camshaft to wear & then the steel from the camshaft gets into the oil which damages the vacuum pump. Does that make sense?
@@kennedysgarage3281 Does replacing the pump fix the problem? you need to deal with the injectors, then with the camshaft and only then with the vacuum pump, right??
@@avtofavoritby2138 replacing the vacuum pump alone does not fix the problem.
First I would suggest removing the injectors just to examine the copper washers underneath, it only takes around 1 hour .

Hi Peter , I ❤ your channel, but wouldn"t you agree that Mazda should STOP producing these crappy 2.2L diesel engines ? They are a total disaster, the excessive carbon buildup, the exhaust camshaft wearing out, and EVERYTHING becomes plugged up with carbon deposits ! I would NEVER, EVER get a Mazda with that Diesel engine ! "Skyactive Technology " my ass !!
😂😂😂😂
They are quite a few items that fail very regularly on these engines alright. They have revised the engine design from around 2017 on, they seem to be quite a bit better 🤞🤞
For me a lot of owners & garages alike are getting stuck on repairing them. And we are getting very familiar with them and every repair on them is getting faster & easier. Which is a good thing for my business & something I haven’t ever had the privilege of doing before, so yes I do like them 😬😬😬
It takes all kinds Richard, as a guy once said about me, I’m either good or stupid 🤷🏼♂️🤷🏼♂️
