I remember back in the 80's I had one of those on my old Firebird. I didn't realize they were back again. Sounds like a vacuum cleaner lol. I didn't expect it to flow that much air from the sound of it. Thanks for the informative video.
Thanks Eric. Seems to be the norm from manufacturers - no rebuildable/replaceable pieces on parts. Buying complete replacements is causing sky-high repairs and angry customers. You end up doing more explaining than fixing, sheesh!
+Corky C True story :)
GM, payin' the bills, as usual! LOL
That Chevelle in the background was close to GM's peak - all downhill from '73 on. :(
Thank. You Eric. I own 2012 Chevy Malibu with 2.4 liter. I learn more about my engine.
Another great video, Eric. Very rare to see you use your digital test light. Good to see a use for it. Sure wish those scan tools were more affordable but that's how they keep you in business. Thanks for throwing out some quick ideas on how to get some results without one. Makes for a super video!
+johnaclark1 Sure thing. You can get the smaller version of this one for around $1500 I think...
+South Main Auto Repair Yeah, I've got four cars. An 08 Ody Touring I bought brand new (149K,) 98 Nissan 200SX (125K ), 2002 GMC Sierra (52K,) and 2011 Jetta (38K,) and do ALL my own work and enjoy it. I'm big on preventative maintenance. Tires and recalls are about the only time I take them to anyone for anything. I've even gotten pretty good at string alignments! I've never been happy after getting my cars back after the dealers have worked on them, for warranty and simple recalls. I'd bring my car to your shop any day, though.
I've considered the Autel after watching you work your magic on it but it's still just a bit too expensive to justify for home use and seems like I read they are $20/mo for subscriptions. I have a little Innova 3130 scan tool I bought shortly after buying my Ody that does live data and I've gotten by with it so far. Your lift, your Autel and your Verus make me jealous every time I see them!
Haha sounds like you have a pretty good fleet there. I know a few guys have mentioned that when they bought a scan tool that that they went in on it with a few buddies and they all split the cost and shared the tool when needed. Didn't know if maybe you had some other gear heads you could or wanted to do that with ya know. Any how just an idea :)
+South Main Auto Repair I wish! That's a super idea. Unfortunately, I moved to Charlotte, NC from Eastern Oregon 3 years ago and I live in a neighborhood where nobody does ANYTHING for themselves. I do EVERYTHING myself and they always look at me in amazement when I'm digging my own drainage ditch in the front yard or simply fixing my own sprinkler head in the front yard. I just grew up that way. My dad never hired anything out. Until I saw him get old and lose the ability I never saw him take a car to a shop. He couldn't afford it. He did everything from successfully rebuilding his own engines and even an automatic transmission out of a 65 Ford, to major house construction. Nobody does that stuff themselves today. People don't know how to fix things. It's sad. There's a rush you get when you find a problem and fix it that many people have just never experienced. You're right I gotta find some local gearhead friends!
Oh I hear ya man! I always try to do what ever I can myself and it is sick that they are taking all of the shop classes out of schools now days to. No more shop, no more welding, no more wood working.... our local school says it is because it is just to dangerous for kids haha. The future does not stand a chance. They are to worried about whether or not everyone can use the transgender bathroom bs than helping raise these children into men and women,
Thanks Eric now I can fix my car you are always helpful
Thanks for the straight poop on the bow tie. Can't wait for your next installment.
Well done Eric.
+STEVE ROB Thanks sir
I'm glad my Malibu is an 08 and doesn't have that stupid system on it! I noticed in the video that Malibu had new variable timing solenoid valves
Good job eric always learn a new fix with you but where is the boss?
That sure is a fancy scope on a rope youre using there LOL I like it Thanks for all your awesome videos
Eric, how do you keep your hands so soft and supple? Any product that you recommend for keeping them from looking like "mans hands"? Oh, by the way. Nice video as always mate!
My secondary air injector itself is bad, i cant find where its located anywhere online! Such a pain. If you have time could you please explain where it is so i can replace it? Would be greatly appreciated. Thanks!
Another quality SMA video!
Good info Eric! Thanks.
+The Disgruntled Mechanic Hey thanks for watching MIke
Awesome as always. You could also use a relay jumper like the Lisle set to turn the pump on. Yes these air pump systems are ridiculous. I deleted the one on my sons 93 F150. Yes it's a Ford but it was his Grandfathers truck ( mothers side, my dad would never drive a Ford lol ). I may have to pick up a digital test light just because.
thanks for the help info.. details 👍
What is an air injection reactor you ask? Here is the wiki answer to that... en.wikipedia.org/wiki/Secondary_air_injection
+South Main Auto Repair I was right at the part where the article mentions diverter valve when you said diverter valve
Please help ... my Malibu 09 ... has no check light on .. rpms rev up when slowing down or letting off gas , my motor will rev up to t times ? Seems to be making my trans not shift well .. what could it be ? ANY HELP WILL GREATLY BE APPRECIATED
Good fix to learn those 2.4s are getting popular
I'm hearing the same noise from your video at 7:35, when you manually open the gauge is the same noise that I'm hearing briefly on cold starts.
GOOD VID , GREAT INFO MUCH APPRECIATED!!!!!!!!!!!!!!!!!
Hey Dr O, what about a "Throwback Thursday" segment where you can dive in to lost technologies like points style ignitions? I bet you still have a flex shaft hex driver for setting dwell on GM's. Other topics could be drum brakes and generator charging systems with external regulators. Let's help the new kids, under 40, with old fart tech. Thanks again,
good video nice 67 chevelle on the lift in the next bay
Nice quick diagnosis
+Hayward's Automotive 1,2 BBQ!
hey eric seems to show max and min range for defaults in the next column over on your scan tool. thx for the vids!
+R HEIDEMAN Oh that is just bogus on that scan tool. Never put any stock in those numbers.
🎯
Very helpful, thank you!
What's doing with the 67 Chevelle that's been on the lift for the last couple of weeks?
+eldoradony Fixing the brakes :)
+South Main Auto Repair All that 'Go baby,go!' needs some 'Stop baby,stop!'
mm
Wonder if the owner of that pretty blue 67 would have an interest in a 400 small block. Its a 1980 2 bolt main short block with a crower perf cam, new chain, water pump, balancer & pulleys. Also have 882 bare heads, non EGR cast 4bbl manifolds, Rochester Quadrajet carbs. Not to far away in PA so would even deliver.
another good video, thanks for the information.
nice scope on a rope... digital version... liking it...
+Mike Pratali It has its place...
I have a 2010 Malibu with the 2.4L, I have a this brief noise on cold starts. After research I've learned that it is an air pump (I'm assuming it's the AIS) that is required for emissions in some states. In your opinion does this sound accurate to you and if so is there a way to quiet it down? Thank you in advance.
besides the code, what were the symptoms?
Eric O, how you doing? Good I hope.
nice Dr o
Good info, thanks.
6:21 Default max-min pressure values are given in "range" column.
That was fun! Thanks master O. :DThat thing is loud tho.
+Atrax R just the way the camera picks it up is all
South Main Auto Repair Ah, yea I thought they wouldn't put something so loud in the car to eat at your nerves all the time. :P
Erik did you make video on that 67 on lift ? I built 66 drag car.
thanks....Where did you get the small yellow test lead you used in testing and cost ?....thanks ....bob
Gah, SAI issues are always fun, and I have a bit of a love-hate relationship with 'em. On the upside, they're usually enough of a pain to diagnose and/or repair that a lot of people throw away older cars. I flip cars every so often, and it's a great way to get a project car cheap! On the other hand, sometimes SAI repairs can get expensive or labor-intensive. At least the labor is free when I'm working for myself!
Rather annoying when they combine sensors and solenoids like this, though.
+rhkips I have always thought AIR systems were pretty easy. Not to many parts really
South Main Auto Repair
You don't work on Germans. ;)
Oh yeah I bet they are a mess haha
Eric I'm waiting for the video where you get a Husqvarna riding mower and swap out the 24hp V-twin for a 395hp Hemi.....:-)
What scan tool do you recommend?
Which do you like better the Autel in the vid or the new Bosch scanner? I know the recording sucks on Autel live data
My 14 Malibu makes a rattle noise only cold starts and soon as I cut it off and turn it back on it doesn’t do it but when it sit for 15 minutes it will do it!
got gas, parked the car in some gravel, started it up and got this code.
an 09 cobalt base xfe model, opened the lower pump seemed fine. then opened that rear pump valve and lots of carbon. did some diesel injection. on first start up i can hear one of the pumps.
does the diaphram rip? or does it just get stuck open and wedges itself from moving? also there is a button on the unit, i dont know what it does or if its just a one way valve. can you cut the old unit in half?
symptoms are choppy drive at steady throttle
Eric, i thought air pumps were obsolete along with egr valves now that we have fancy stuff like variable valve timing...guess i was wrong.
+Paul Carroll Oh yeah we still see a lot of both actually
+South Main Auto Repair if that chevelle behind you in the video has an air pump(think the first year was 1965) then you were literally standing between gm's first and latest air pumps. The irony...haha
Ummm this one has a 4bbl and headers... pretty sure the emissions is long gone haha
+South Main Auto Repair they usually are lol. cant wait to see the videos of the chevelle. Hope everything is good with you, keep up the excellent videos.
Good job !!
was the car running ERIC because just wondering how making the load noises
Thanks
@southmainauto is there any consideration when removing the hose that runs to that valve? Unfortunately GM designed it in such a way that it blocks one of the thermostat bolts, which is coincidentally what I need to replace!
Cool video
Thumbs up great video. Had to watch it three times to understand it all. Some advanced stuff at 5:39, plugging test light reduced voltage into the signal return wire to confirm circuit is good with the help of a scanner. If I accidentally sent 12 volts into the signal wire using a Powerprobe, would I blow the pcm?
+Sandbag1300 Nope, sensing circuits are high-impedance so straight 12V won't harm them at all. Eric's digital test light looks pretty slick though!
+motoYam82 Your right ivan as alway's.
Secondary Air Injection?........................Is it a modern version of the Pollution System Oxygen Pump used on the older engines that pumped air into the exhaust manifolds (each exhaust port) to help burn spent gases from the combustion chambers?
+Jeffrey dontyouwish Pretty much sums it up
*Digital test light???*
Let's hear your opinion of them in a video, please.
I just had this problem on my 10 Impala are these really that common on Chevy's
what would you recommend for a scanner or possibly a cheap scope so that I could check for a possible coil crapping out intermittently. I'm trying not to inconvenience my buddy for his snap on. I was wondering if you knew a cheaper home owner/ weekend warrior so to speak, scanner/scope.i have no check light so I'm kinda at a stand still
quick and easy how we like it ;-)
Ok, so you fixed this Malibu, what about that Malibu in the other bay?
Do those east coast wiper blades come with paper attached or is that extra?
What if you don;t fix it ?
Do the Subaru PZEO engines work in the same fashion? Are they worth the extra cost if something like this happens?
Hey Eric, was wondering why you don't have any Nissan videos? Love the channel and so far the chainsaw vid is the best... Lot's of laughs on that one.
+Jake 78 (JTTexas2001) Dunno? We don't see many of them actually
+South Main Auto Repair Seems to be the same with Hondas. I think I've seen vids with a Civic, a Pilot (for timing belt change) and a CRV is all.
Speaking of Honda timing belts (I know, not really,) Eric, have you seen these Lisle Honda Crank bolt impact sockets? It's super thick and heavy. The extra mass of the socket is supposed to knock the crank bolt right off with an impact. I've heard people rave about it on the Ody forums. I didn't know about it when I did my timing belt a couple years ago. Wish I had. It was a starter bump trick that got it off for me.
www.amazon.com/Lisle-77080-Harmonic-Balancer-Socket%C2%A0/dp/B00RGNCV1U/ref=sr_1_1?ie=UTF8&qid=1463623668
Yep I did a vid on it :)
+South Main Auto Repair Oh, snap. Ima big dummy. I see that now. I watched that video too and totally forgot you used that socket in it.
Well thanks anyways. I really appreciate the work you put into these videos. Can't say enough about it. Thank you.
How do you like your new test light? Is that a Mac Tool test light?
I've seen you use a digital test light twice now. Has your opinion of them changed since you told me they were useless(maybe you said mostly useless)? I'm not being a smartass either, I genuinely want to know if your opinion has changed. I don't remember which video I had asked that on.
I ended up buying that coiled cord test light from your Amazon store. The Official Scanner Danner one. I like it a lot.
+ejbcomp Oh sure haha yes they are a mostly useless tool, IMO but in certain situations like this they can be used and like in the last vid I did it was actually the perfect tool to use because we were passing such low current down that wire.
What scan tool do u use
I got the same car, with that famous code po2135. we already changed the pedal and throttle body and it still goes into engine power reduce mode. dealer already changed the ecm, figuring that was that but still its doing that. What do you think it might be?
I'm with Mr Carroll, I thought air injection had gone the way of the carburetor and the metal oil can.
Come on Eric let us in on the chevelle
+Dan Ward Sr , I have been waiting all week for the doctor to let us see the rest of that classic. I did catch a 396 badge in another video. Eric, please show us around that pavement pounder.
+atschirner Pavement pounder hahaha not hardly. Total weak sauce by today's standard. Seriously though you could knock the doors off that thing with most mini vans lol. It just came in because none of the brakes worked. It got a full brake overhaul is all.
👍 Eric as always
Thanks +Heather Horstdaniel
Eric, is your Actron CP9670 capable of doing these test's? I am considering purchasing the Actron for home and you haven't done a review of it yet.
Don't see many with air injection around my parts must be a California emissions car. The only ones we see are trailblazers with air injection.
good video
+Hawaiian F150 Thanks man :)
Could I hook up my manometer to see the pressure change?
I like it.
We did this to the same car and now the idle is at 3000 rpm until we put it in drive
Mine says fault on these on my car using my tool. So what is this thing called to order
Eric O. where do u get those sweet diagrams witch help visualize the problem?
+Lucy P. www.prodemand.com
Is there a kit to update your car to have autopilot, you know so I can watch SMA videos while riding down the road.
I will have to look into this sir. wait would it make me at fault if you wreck?
No........Unless it was a real interesting video.
Never thought I would see the day that Americans were to Lazy to drive there own car.
Always wondered about the Ins aspect, Now I know before you can turn it on, you have to accept terms that you must have both hands on wheel, and pay attention at all times, or you cant turn it on. Auto Pilot my A**.
Charles Miller Think of the benefit, program the car to take your kids to school and bring them back. Maybe even have the car come back home so you can use it. You would not even need DD after a nite out.
I would like to see cars, with a built in troubleshooting computer, whenever your having a problem, it just tells you in plain language whats wrong, and how to repair. My old 82 has a ladies voice that tells me when my door is not totally closed
wich one is the signal return wire I can't figure it out
I am having the same problem any help would be appreciated
what kind of test light is that and where can i find one?
I have a 2011 Malibu my car will not accelerate when in drive or reverse. I cut the vehicle off then restart tge vehicle the car will then drive about 5 mins then accelerate slow down. What may this be???
Great
deadhead pressure? wish I could see a show.to bad
Remember the good old days when cars didn't have pointless plastic engine covers? Lol. Wonder how much time you've lost over the years to removing and putting these dang things back on!
Wow FAST PACED!
I miss the good ol days when you only needed air/spark/fuel.
Thanks for the video & Info....God Bless You ¡¡¡¡¡
I was working on a chevy truck with the same system. The intake fresh air hose was in a location that every time you drove thru a puddle of water it would suck water in. So I moved to to a higher location.
the great blue Chevy please
did the veris break down again?
+Steven Tenney No, he's been swapping them around some.
He has the Verus Pro now which is wireless and needs no keys. He traded in the Verus @6 months ago on the Verus Pro.
Where can you buy the digital test light?
Thanks for the video.
+amtpdb1 I don't recall where I got that one actually
+South Main Auto Repair I will look around. I enjoy watching your videos and look forward to them.
Have a nice rest of the week.
+amtpdb1 Looks like a Lisle 28830. Pretty new and not on amazon or available locally for me. Cornwell also sells it as LS28830.
Looks like this job really blows.
Amirite?
+Spooky_Ghost Ummmm... yeah hahah
#South Main Auto Repair
I have a problem I have been watching your videos for a while and I think you can help me with this issue:
- I have a 2002 mercedes w203 c200 kompressor sedan automatic , When I start it snd put it into reverse it stalls but if I turn it on and wait abit and put it into reverse it works fine this only happens if I dont turn the car on for like a day or so please help.
What actually this whole sistem is for? Seems ridiculous
+Stjepan Đopar It seems to pump air into the exhaust in order to make the catalytic converter burn more of the unburned fuel when it's running rich at startup. Or something like that.
+celeron55 Nah, that doesnt make sense since Eric said that it connects to the head of the engine...well, I bet that it has to do something about that ecology junk
+Stjepan Đopar Well, the exhaust starts from the head and it's easier to bolt something to the head and have an extra channel in there than directly to the exhaust manifold.
+celeron55 I dont think so...maybe Eric will answer
+celeron55 Yep. That's what it does. Just more emissions crap....
