Hi Everyone, Well, FINALLY!! I think I have figured out the high and unstable idle. We go back through everything to see what I missed... Let me know your thoughts below!
The meter you use in troubleshooting this problem is a very useful tool. Can you tell me the make and model please. Great job on patiently getting to the bottom of this issue.
@@bobboyle6649 Hi Bob, Here is a link: amzn.to/2zb629o It is ok... There may be some of better quality out there, but this is pretty reasonably priced. Thanks!
Nice solve! I bet the injectors got clogged and it was running poorly so someone just adjusted the throttle instead of getting new injectors or getting them cleaned.
@@HeidiandFranny I'm looking to buy a classic air cooled VW Beetle and have been so inspired by your inspirational how to videos on maintenance and repairs. Thank you for your brilliant content. Love to you both from Yorkshire, United Kingdom x
Have worked on these engines since new, here are several other things I always check when there are idle issues: 1- Make sure throttle linkage is adjusted correctly, and is allowing throttle butterfly to fully return to its stop. This requires checking from gas pedal to top of engine, and especially at the bellcranks on the side of the transmission and the top of the engine. 2- Make sure throttle butterfly stop screw is adjusted correctly. On this FI system it is not used to set idle, only to keep butterfly from wearing throttle bore when closing. 1/2 turn open is the proper adjustment. If one tries to correct a low idle using this screw, it will ruin the adjustment of the idle switch. 3- Make sure the idle switch is good and is adjusted properly. Surprised not to see this mentioned, as it can definitely cause idle to hunt if it’s not. It’s on the rear of the throttle housing and is adjusted by loosening and moving it. Easiest to adjust both stop and switch with the throttle housing off the engine. This is a bit of a tricky adjustment but info explaining the procedure is in the Porsche manual. 4- Check short rubber hose crimped onto left end of vacuum pipe which runs from the intake boot (btwn airflow meter and throttle housing) to the Y-shaped vacuum venturi for the power brakes. These deteriorate after 35 years and can leak. Great videos - wish I had your patience! Sorry I didn’t come across this video series before now. The older I get the more I learn!
Franny, I’m always impressed by the most important tool you use on your rebuilds-your brain! Your attention to detail and inquisitive method are informative and entertaining, keep up the great work! -Don
You need a show on MotorTrend, no joke! I remember finding your channel from Dan (NGS) and being hooked. Love this project series and that you're not only doing the work, but also sharing it.
Love your channel! I hope you see this comment. Your diagnosis of the idle being too high is spot on. I do have a couple observations for you. Yes- When the DME detects an engine speed over 1200 RPM and the throttle switch is in IDLE position it cuts the fuel to the injectors. This isn't really to prevent runaway- It is to save gas and cut emissions to zero when you take your foot completely off the throttle while driving while the engine RPM is above 1200. It is still possible that a faulty ICV might still be the issue. I think this might be the case, as after you adjusted the idle on the throttle body and ran the DME in normal mode, the idle didn't seem that steady, and the engine was not running that smoothly. An other issue is that when you disconnected the Oxygen Sensor the idle speed went up considerably. This means in open loop the system is running rich. In may even be running so rich that the DME can't completely adjust the AF ratio. An overly rich AF would also contribute to a high IDLE. When rich the O2 sensor will read around 0.9 volts, and when lean 0.2 volts. It will be interesting to hear what you find from the shop when you have them check the O2 levels.
Great stuff Franny. I've owned a 87 911 cab for twenty years. Later year 911's are on a different level when it comes to working on them, and this was a great example. Over the top engineering makes them a different breed. Thanks for sharing your knowledge, it is a big help.
My near mint 87 911 has been sitting for 8 yrs. I’ve owned it for 28 yrs. Taking in next month to get road ready again. After watching all the episodes here I know what the shop will have to pay attention to, thank you.
Great show, I have worked with engines on ships for over 20 years, In the past I have also worked with cars as hobby. Today I am behind a desk and I like the troble shooting, sometimes frustrating but so rewarding when solved!! Great work and you speak clearly so that a non english speaker understand 99,9% thank you!
Fifty-five years ago I had one of the first Porsche 911s in the US, a 1966 model, chassis number 901180, the 180th 911 ever built. Six Solex carburetors (actually, two 3-barrel units sharing a common float bowl) and the only transistors in that entire car were in the Blaupunkt radio. I'd pull the engine and transmission out as a unit: Four mounting bolts, one fuel line, a throttle cable, a few wires, and a 10mm bolt to disconnect the shift linkage. It was a 10 minute job including the time spent putting the car up on jackstands. Those were sure simpler times.
I'm going through the agony with a Bentley Turbo R and a Rolls Royce Shadow II (brakes)! I remind myself of your patience and keep going! I'm ALMOST where you are! Respect your dedication!
Hello Heidi and Franny's Garage, This channel is FAR TOO underrated! Very happy to see progress on such a beautiful 911 cabrio! And it is SO clean!....a testament to your will, skill, and attention to detail. In my opinion, believe you hit the target on the coil replacement, but as often happens, there were other issues. Your diagnostics and detail with the idle control is priceless! Keep posting! I will continue to follow and hope to introduce others to your channel. PS: Get that scope out! Cheers, Mr .P
I have an SC and had a similar experience. As the car ages and sees one owner after the next the real issue (O2, vac leaks, plugs, coil, valve adjust, distributor or whatever) never gets fixed and what happens is that it just gets "tuned out" and "fixed" by messing with the fuel mixture or idle setting. It's amazing what actually happens to the cars over the years. Love your videos. They are a joy to watch!
Good diagnosis. A note about oxygen sensors there are two different types of o2sensors. Wide band and narrow band. The O2 sensor that you have is a narrow band and should continually change between 100mv -900mv. The ecm use this input after the engine warms up and goes into close loop along with other information sensors to keep the air fuel ratio at the proper level. Thank you for your videos. They are very helpful and organized. And thank you for sharing your knowledge skills. R. G. Young, Jr.
Ha, I was screaming at the TV to bridge the idle control pins and set the base idle (but as you pointed out the CO needs to be correct at that base idle so nice to see you did that at the shop 👍. Also with the oil thermostat open at 90C (right front wing warm) the oil level gauge needs to be near the top. IF your stat is open, you need a tad more oil in your tank. Great video Fran!! We used to have a special tool made out of one of the round relays with two LEDs and a switch on top for that, or just use a cut down Blaupunkt radio key to bridge them. The LEDs were used to give fault code read outs on the later 944 Turbo until the Bosch Hammer came out. Happy memories for me Fran, lovin your work.
Impressed with you dedication to the car. And the impeccable state of your garage. Your project car now seems in a superior state compared to my 3.2 convertible, 1986 with 230.000 km and counting. But enjoy it every summer without complaints. I recognise the surging. My car does that for a short while after a complete cold start. Never gave it a thought. I now understand this must be due to the oxygen sensor needing to warm up. Keep up the great work. Best regards from the Netherlands.
Hi Franny, well done. Yeah, sometimes troubleshooters are like heavy backpacks that don't lose weight. At the end you fixed it and that always's make a client happy.
Excellent work. So the injectors were gummy, someone compensated for them by adjusting the idle ( which is an old shade tree mechanics move) you cleaned the injectors and needed to reset the idle. The spark plugs, wires, coil, O2 sensor tried to get into the act because their egos were bruised, I don’t blame them, so they got replaced. Beautiful work getting the 3.2 symphony to play again Franny. This series is a great tutorial on the 3.2, thanks for posting it. I learned a lot about my car.
Well done your perseverance finally paid off. Usual problem, as things wear we adjust to maintain performance and then when we replace with new parts all the adjustments are out. Great video as usual. Looking forward to the next video. 👍🏻🇬🇧
Hi Heidi and Franny Just an update on our 1991 964 high idle issue. After exhausting my limited testing skills, I ended up taking the car to our local Porsche dealer. They have one mechanic in particular that is an expert on older Porsches. The problem ended up being a faulty oxygen sensor and more importantly three of the couplers that connect the intake manifold to the cylinders were cracked, one was split in two. Amazing that the car ran as well as it did.
My 85 911 idles around 1k. I definitely need to replace my O2 sensor then maybe take a look at that base. Your videos are so insightful. Thank you so much for taking us along with you on your projects. Excellent video production! ❤️
Super interesting - perhaps poor fuel injector flow was incorrectly adjusted to compensate, thereby changing the base idle too high. Then with rebuilt injectors/plug wires/O2 sensor/coil it needed to be reset.
Really impressed with your approach to this problem. Glad you are getting on top of it now. I bet very few Porsche specialist garages would be so thorough. Great channel. Thanks
Wow, well done. Persistence, skill and just a bit of luck? No, it wasn't luck. Persistence and skill. Thumbs up from the UK. I like what you do, keep going please.
I have been following you for quite awhile now. I am very impressed with your calm and logical way of diagnosing and solving difficult problems. “What would Franny do?” will be my mantra in the garage from now on. Keep up the great content!!! 🙏🏼
Well we all learned a lot going through all the possibilities. I have a 72 with a 3.2 and installing PMO throttle bodies....let's see if I can get into an trouble 😀. Thanks for the great video.
You've gone through, what appears to be, all of the major components of the ignition and fuel system and have that thing working like a "top". I like how each aspect of your work is explained as to what you are doing and why. I'm looking forward to more tidbits from you on the engine repair and then on to the interior (please keep the red leather...that looks so good and maybe some carbon fiber bits).
I am impressed with your problem solving research and skills. I always learn something along the way. That look Franny gave Heidi when she pulled back into the garage from the first shake down drive. My wife knows that exasperated look from me when sorting out the Mini. So pleased you two were able to get this idle issue sorted.
Well a great job pin pointing those issues. I think your right each system was compensating for another part. Once you fixed one issue it lead to the next. Way to chase that 🐀.
A really interesting video to watch. As usual, you did an excellent job of explaining everything as you went through the process. Thank you for sharing your experience.
Glad to see that you solved the issue! 4-1/2 turns in?? Wow, that definitely was quite a bit off! Thanks as always for the detailed steps and descriptions you go though with us. It's like a college lecture, but the only difference is that this is a topic that I'm TRULY interested in! :) Lol.
Awesome job Franny! Thank you for sharing the ups and downs of projects like this! Some UA-camrs would like it to appear nothing goes wrong in a project of this magnitude.
First, that clean engine compartment in the opening sequence was beautiful. We had a similar idle issue with the 911SC but that was a CIS engine; no popping though. I recall we did something about the O2 sensor and the mixture adjustment certainly needed to be turned, using a tailpipe sniffer. I'm happy to see this issue behind you, as I know are. I think the 4 turns of the screw were certainly due to injector issues. Great troubleshooting and thanks for another great video. Cheers to both of you!
You guys are doing a great service with your channel and this project! I love cars, but don't currently own a Porsche (financially challenged with family), but that flat 6 is a thing of beauty. I would love to get my hands dirty on that engine, but the next best thing is watching you guys. Thanks again for taking us along on the journey.
Hi Heidi and Franny.I follow you and Pats Garage from Spain and I just want to say that you are real inspiration.Thanks a million for sharing tour knowledge.
Glad that you found the problem, I would have been banging my head against the wall with this intermittent problem long ago. Keeping my fingers crossed that with the CO measurement and fine tune you are back to normal! Very interesting troubleshooting, you did great with it.
Great video! The pace, the information, light, cliffhangers everything is just 10/10. Love your videos Franny & Heidi! You make the entire lock down goes from unbearable to bearable. 🙏🏼
Franny I'm so happy that it was such an easy fix and now you've got a great running Porsche! I absolutely can't wait for your Ferrari 308 videos to come. I learn so much from your videos. Thank you for making them!
Wonderful, persistence pays off! Last video you were actually 95% there. In the end just a basic adjustment. Someone before you had no idea what they were doing and tried the easy way with idle settings. Older car is gonna have older problems but you worked through it. This was fun to watch and I have to say a bit easier than my 12 plug 993. Try one of those. Congratulations!
Yes, we have a 1994/5 993 as well. Beautiful car, but holy cow! 12 plugs and two distributors... When we bought it a few years ago we had the shop replace all the plugs and wires and the belt on the distributor just incase. I bet that is a good afternoon job!
I don't even have an air-cooled Porsche. (Air-cooled VWs here) But I was hooked at every moment in the video. My partner and I just found your channel and were loving it. Subscribing after this comment. 🌈❤ 🚗
Congratulations on completing your 'engine out' on the Porsche. I would not say I knew, but I watched all of these and you didn't miss anything while doing the job! It was not going to be something complex. Glad you found it. Have a good weekend. John UK.
Well done, Franny! Great news, but sad if it means the end of this series. Those Colorado skies look beautiful. When I was driving 944s in the UK many years ago there was always a thing in the Porsche community about Porsches running better in cold weather. I never noticed it myself! What next?
Thanks so much! I still have interior work and final detailing and... We will share all the costs as well. Should be interesting (not sure I want to know that...). The Ferrari is up next with full suspension rebuild and interior work. I do want to go into the history on that car a bit as well... Should be fun. The little 356 needs brakes and steering work so maybe mid summer on that? We'll do our best to keep you entertained :)
@@HeidiandFranny You won't be getting bored then! I like your approach and look forward to these upcoming projects. Regarding costs, these cars are flying up in value. I live in Thailand now and even though I will never own another Porsche I keep an eye on UK prices. Good 997's are now more affordable than these old Carreras! Your one is very well sorted mechanically, the body looks to be very sound and there is only some cosmetic work to do inside and out. You've invested a lot, but everything has been done the correct way and I still think you are quids in!

Have you ever worked on a tiptronic transmission that jumps from manuel into automatic mode?
Have worked on these engines since new, here are several other things I always check when there are idle issues: 1- Make sure throttle linkage is adjusted correctly, and is allowing throttle butterfly to fully return to its stop. This requires checking from gas pedal to top of engine, and especially at the bellcranks on the side of the transmission and the top of the engine. 2- Make sure throttle butterfly stop screw is adjusted correctly.

In my opinion, believe you hit the target on the coil replacement, but as often happens, there were other issues. Your diagnostics and detail with the idle control is priceless!
Keep posting! I will continue to follow and hope to introduce others to your channel.

Cheers,

Thanks so much!! Will do on the scope. I have been studying all manner of graphs and such to get an idea what to look for :)

None of those diagnostics were wasted. Now you know what you have got and it should give you lots of confidence going forward.
I certainly learned a lot!
You finally managed to fix it. I like how you pay so much attention to every detail. You work like a watchmaker.
This is pretty awesome how you got to the root of the problem!
Great job with the troubleshooting!
Good diagnosis. A note about oxygen sensors there are two different types of o2sensors. Wide band and narrow band. The O2 sensor that you have is a narrow band and should continually change between 100mv -900mv.

Thanks so much for that. That sounds like what the manual said as well. So, Narrow band. Good to know!
That was a long road to travel to get to the actual culprit. It did made for a very entertaining series of videos, lol. Glad you found it!!

At the end you fixed it and that always's make a client happy.
It's a pleasure to hear this engine idling perfectly. Great job!
Probably find the injectors were needing done and previous owner turned the idle up to keep it running.
Thank you so much for everything you have shown us and for explaining it so clearly. There is no way you can learn this from just reading a manual.
Excellent work. So the injectors were gummy, someone compensated for them by adjusting the idle ( which is an old shade tree mechanics move) you cleaned the injectors and needed to reset the idle. The spark plugs, wires, coil, O2 sensor tried to get into the act because their egos were bruised, I don’t blame them, so they got replaced. Beautiful work getting the 3.2 symphony to play again Franny. This series is a great tutorial on the 3.2, thanks for posting it. I learned a lot about my car.
Thanks so much. It really is a symphony :) I'm still very curious about the coil. It may make a reprise performance :)
Happy for you!

Thanks so much and good luck hunting down your idle. I think the car has always idled pretty high. 800 sounds really slow now ;)
Super interesting - perhaps poor fuel injector flow was incorrectly adjusted to compensate, thereby changing the base idle too high. Then with rebuilt injectors/plug wires/O2 sensor/coil it needed to be reset.
All I can say Franny is it is a damn good thing you guys are professionals. Buying a low priced Porsche "as is" is a big gamble in my opinion.
It really can be. This car has good bones but it easily could have gone the other way...
Very well done Franny, glad you fixed your Porsche and now increased reliability with replacing some worn parts.
Thanks! Totally! I'm pretty sure that DME relay was about to let go on me... The coil and I still have a follow-up scheduled ;)
Patient and methodical work
Brilliant as always Franny. I love your forensic approach to trouble-shooting. Absolutely top drawer.
Gosh, thanks so much!

I am impressed with your problem solving research and skills. I always learn something along the way. That look Franny gave Heidi when she pulled back into the garage from the first shake down drive. My wife knows that exasperated look from me when sorting out the Mini. So pleased you two were able to get this idle issue sorted.
Thanks so much!
Well a great job pin pointing those issues. I think your right each system was compensating for another part. Once you fixed one issue it lead to the next. Way to chase that 🐀.
Totally! I got very familiar with my tail ;)
A really interesting video to watch. As usual, you did an excellent job of explaining everything as you went through the process. Thank you for sharing your experience.
Glad you enjoyed it :)
Impressive engineering work and sleuthing! This is a part of why I love this channel.
Thanks so much Jeff :)
Great trouble shooting Franny! Love the way you take your time and run down your possible culprits.
Glad to see that you solved the issue! 4-1/2 turns in?? Wow, that definitely was quite a bit off! Thanks as always for the detailed steps and descriptions you go though with us. It's like a college lecture, but the only difference is that this is a topic that I'm TRULY interested in! :) Lol.
Awesome job Franny! Thank you for sharing the ups and downs of projects like this! Some UA-camrs would like it to appear nothing goes wrong in a project of this magnitude.
First, that clean engine compartment in the opening sequence was beautiful. We had a similar idle issue with the 911SC but that was a CIS engine; no popping though. I recall we did something about the O2 sensor and the mixture adjustment certainly needed to be turned, using a tailpipe sniffer. I'm happy to see this issue behind you, as I know are. I think the 4 turns of the screw were certainly due to injector issues. Great troubleshooting and thanks for another great video. Cheers to both of you!
Thanks so much!
You guys are doing a great service with your channel and this project! I love cars, but don't currently own a Porsche (financially challenged with family), but that flat 6 is a thing of beauty. I would love to get my hands dirty on that engine, but the next best thing is watching you guys. Thanks again for taking us along on the journey.
Hi Heidi and Franny.I follow you and Pats Garage from Spain and I just want to say that you are real inspiration.Thanks a million for sharing tour knowledge.
Thanks so much! Pat is a really great guy :)
Great to see you were able to troubleshoot the high idle issue. Love your channel.
Thanks so much!
that idle is so satisfying!
Glad that you found the problem, I would have been banging my head against the wall with this intermittent problem long ago. Keeping my fingers crossed that with the CO measurement and fine tune you are back to normal! Very interesting troubleshooting, you did great with it.
Thanks so much!
Well done Franny!
Great video! The pace, the information, light, cliffhangers everything is just 10/10. Love your videos Franny & Heidi! You make the entire lock down goes from unbearable to bearable. 🙏🏼
Awww, Thanks so much!
I think you did super. Now you know all things is tip top. And it sounds wonderful. Great job.
Thanks so much!
ah, the view down the hood during the "toodle", the view reminded me of the same view when i had my 76 911S.....
Franny I'm so happy that it was such an easy fix and now you've got a great running Porsche! I absolutely can't wait for your Ferrari 308 videos to come. I learn so much from your videos. Thank you for making them!
Thanks so much!
Wow... really glad you got it.
Excellent video and EXCELLENT diagnostics!
I ran into the same issue with my 944. That idle control valve was way off and it was hunting. Glad that you were able to get it all sorted.
Wonderful, persistence pays off! Last video you were actually 95% there. In the end just a basic adjustment. Someone before you had no idea what they were doing and tried the easy way with idle settings. Older car is gonna have older problems but you worked through it. This was fun to watch and I have to say a bit easier than my 12 plug 993. Try one of those. Congratulations!
Yes, we have a 1994/5 993 as well. Beautiful car, but holy cow! 12 plugs and two distributors... When we bought it a few years ago we had the shop replace all the plugs and wires and the belt on the distributor just incase. I bet that is a good afternoon job!
Yes, mine is a ‘95 coupe. Love it...but so hard to work on. It’s all so cramped and hidden. These cars really teach you patience!
Love watching yr step down procedures to deal with issues. Thank you.
You are a STAR Franny!
Well done on the troubleshooting!
WELL DONE from Sydney, Australia
Perseverance pays off! Well done and great troubleshooting-resolution series.
Thanks so much!
Awesome video... what a great car to have running smoothly like that!
Nice work, can't beat logic, wins every time, keep up the good work
I don't even have an air-cooled Porsche. (Air-cooled VWs here) But I was hooked at every moment in the video. My partner and I just found your channel and were loving it. Subscribing after this comment. 🌈❤ 🚗
Thanks so much and Welcome! :)
I just subscribed to your channel. Really good stuff, excellent video quality and editing and you’re diagnostic and wrenching skills are great.
Nice work, and great trouble-shooting!
Congratulations on completing your 'engine out' on the Porsche. I would not say I knew, but I watched all of these and you didn't miss anything while doing the job! It was not going to be something complex. Glad you found it. Have a good weekend. John UK.
Thanks so much! You too John :)
Excellent troubleshooting.
Well done, Franny! Great news, but sad if it means the end of this series. Those Colorado skies look beautiful. When I was driving 944s in the UK many years ago there was always a thing in the Porsche community about Porsches running better in cold weather. I never noticed it myself! What next?
Thanks so much! I still have interior work and final detailing and... We will share all the costs as well. Should be interesting (not sure I want to know that...). The Ferrari is up next with full suspension rebuild and interior work. I do want to go into the history on that car a bit as well... Should be fun. The little 356 needs brakes and steering work so maybe mid summer on that? We'll do our best to keep you entertained :)
@@HeidiandFranny You won't be getting bored then! I like your approach and look forward to these upcoming projects. Regarding costs, these cars are flying up in value. I live in Thailand now and even though I will never own another Porsche I keep an eye on UK prices. Good 997's are now more affordable than these old Carreras! Your one is very well sorted mechanically, the body looks to be very sound and there is only some cosmetic work to do inside and out. You've invested a lot, but everything has been done the correct way and I still think you are quids in!
