[@mikebell1961]

Franny, Is there a specific mechanical reason that would have precluded removing the suspected failed injector #5 I think and firing the engine over to see if the injector was actually delivering fuel while still powered by the harness???? placing the injector tip into a clear bottle to see if it delivered fuel when the engine was running?

[@reginaldbowls7180]

Thank you. I enjoy how you show the issues that arise after a rebuild, and how you resolve them. Even after the time, effort and money you two have spent. Just amazing. It's doesn't make me feel so bad if I missed something during a car repair. Hopefully KZbin helps with cost. Keep it up. I see a lot of Mk1 Golf fittings and minor parts on your car. Never realized how much parts sharing went on.

Franny, as always this video was excellent. I especially liked your general talk about the diagnostic process starting at 11:42. Your common sense approach to eliminating unlikely paths is excellent and I think you explained it well. There is no doubt it will help us amateur mechanics avoid jumping to conclusions and fruitlessly rushing to time-consuming or expensive actions.

This is my first time viewing one of your videos. I have to say that you are probably the best content producers for instructional automotive troubleshooting I've seen. I'm a car guy from waaay back. I was taught automotive electrical and A/C when I was 18 yrs old, back in 1983 in a shop that had been in business in Downtown Los Angeles, since 1933 maybe earlier. I plan on buying an older 911 basket case and fixing her up, hopefully within the next couple years when I have the garage space. I'll be watching more and subscribing Thanks

[@johnyoung1606]

Hi Franny, Always a pleasure to watch You,,, the methodical process use is the proper way .... My friend who is a early 911 guru, I have had similar experiences but many years ago (1973.5 removed the FI and put tripple Webbers on ,it ran fairly well but smoked profusely , so top end job and back together,, wish us luck,,, engine back in car a in a few days ...

Hi Franny and Heidi, great Diagnostics.!! I absolutely love your videos. If it’s Heidi that’s doing the editing kudos! You both do such great work. When I am flying behind my wife’s 1975 mechanically injected, horizontally opposed six cylinder, air cooled two plugs per cylinder Continental IO-550, we won’t take off without all six cylinders firing evenly on each set of plugs. I am so lucky to have an EGT/CHT that shows me instantly if an injector is clogged or a plug is fouled.. Keep up all the good work. Looking forward to your next video.💕

Great diagnostic work! Such a great feeling when you come up with the answer. Love your channel. Thank you for doing what you do! Have a great weekend!

[@HeidiandFranny]

Thanks so much! You too :)

[@johnnyturbo8460]

Look for vacuum leaks passed the mass air flow sensor for idle issues (check intake gasket, vacuum lines, check mass air flow sensor itself) That plug looks like the injector is not spraying in a mist formation. Maybe clogged or faulty or getting a poor signal. Check fuel system wiring. Sometimes the head of the ejector can get damaged in the prosses of the rebuild. If you drop, or set down the injector rail on a dirty table its possible the injector can get debris in it. Possible the tip of injector could have damage. Good call, swap out injector to "see if the problem follows the injector " Edit: I have actually had a faulty injector that was "bench tested/flow tested" too. Lesson learned, once you get them back AGAIN , test them with a 9v GOOD LUCK

[@allenc5108]

Wow, great video. I really enjoy your methodology working the problem. I owned an '87 for 8 years. As a retired mechanic, at least half the joy of ownership was doing my own mechanical work. It's a pleasure to revisit an old love, sadly missed. Thanks!

I’ve been watching BAT auctions since a while dreaming of owning a pre-993 air cooled 911 one day. Now that I found your channel I realize how demanding it might be to restore and maintain these cars. Thank you for showing us your passionate work on these beautiful machines!

[@HeidiandFranny]

Thanks! Maintenance isn't that bad is you start with a sorted car. IMHO the valve clearance adjustment is the worst of it... The rest is just oil changes and such. But getting a sorted car may take a bit of work and $$ up front.

[@HeidiandFranny]

993 is very different.it is newer for one. Heidi

[@dale193]

Nice! I just saw this, thanks for this content. A couple of notes: 1) If you're trying to isolate injector vs. harness, you can just leave the injector in place and switch the harness connector between #4 and #5 (for example) if you have enough slack in the wiring -- might have to snip the zip ties. Carrera DME are batch-fired injectors, not sequence-fired, so this tip doesn't work w/all cars. 2) While your spark plug looks like it's firing fine, it also looks like a Bosch Platinum +4 plug. In my experience the SC and Carrera ignition systems tend to fire more reliably with copper electrode plugs such as the NGK BPR series or the Bosch DC. YMMV, but worth a thought. 3) So appreciate your taking the time to mention having a fire extinguisher handy -- kudos to you. I have to admit though it gives me the shivers a little bit when I see your ponytail close to the AC compressor & belt. It's probably just the camera angle/depth of field and you're not close at all, but a couple of times when you look at the camera your hair looks like it's just inches from getting snagged in the compressor pulley. Thanks again for the thoughtful diagnostic approach and easy-to-understand descriptions. Subscribed!

[@billgaytes6845]

I had exactly this issue with an injector after a full rebuild and the injectors cleaned and tested (like yours). It appears that the "stuff" they use for cleaning washes all the gum and varnish out of the injector and through that little hole at the bottom. Sometimes, as you have found, the "stuff" laden with all the gunk dries around the needle and it sticks. I gave my injector body a sharp tap on a hard surface (vice) and that frees them up. Saves sending them back and waiting. Great video can't wait for the next episode.

[@HeidiandFranny]

Thanks!

Hi Franny and Heidi, I stumbled across your channel a little while ago and I got hooked to it immediately. I binged through the many videos on your YT channel as if it were Netflix and I can only tip my imaginary hat to you. Really, really informative and helpful, very well made, excellently narrated and such a difference if compared to similar channels on YT. I used to swing a wrench myself a lot in my younger days working on my 914/6 which I owned back in the day. Then I started a family and cars became more of a daily driver issue than an obesssion. By the way, Colorado seems to be really beautiful, therefore I'm looking forward to more country rides on your channel. Keep up the great work, all the best from Munich, Germany.

Battery borrowed from a smoke detector / CO detector :P. I've had cars that sat for a very long time get stuck injectors, and a few sharp taps with the handle of a screwdriver frees them back up, and the problem doesn't happen again as long as the injectors don't get dried out. The bad injector doesn't have an open circuit because I saw an inductive back EMF spark when you disconnected the 9V battery. Thanks for another great video! I was very relieved when I saw the problem follow the injector.

[@HeidiandFranny]

First thing we do is to replace the smoke detector batteries when we install the new detectors. I think I put eight or ten new ones up. Lots of those red batteries left over ;)

Absolutely fantastic, my guess was right although I had the mid cylinder left bank & not the right 😊 . Look forward to hearing it run smooth

[@johnwilmer2551]

Just a random note on my 1984 Targa 3.2 rebuild. After a complete rebuild we reinstalled the 3.2 . Would barely run /miss and backfire ~ also made the Catalytic converter glow red hot . We tried everything. plugs. wires. etc etc. Problem was we replaced the old flywheel with a new one & the kit must have not been machined correctly Or world Pac gave us the wrong Sachs flywheel throwing the 2 DME timing sensors off . My mechanic asked me " hey ! do you have the original flywheel ? Im so glad I kept it ! We dropped the engine reinstalled with the Original flywheel . It fired up first crank and purred like a kitten !

That engine bay is so clean, I can't stand it! Well done. One thing I've learned rebuilding Porsche and Volkswagen engines that are air cooled is, you have to either rebuild the wiring harness yourself or buy one from someone who makes them.

[@pfan12000]

Awesome video best I've ever seen on the 3.2 Carrera. One minor point going through the process is the distributor in that series 911 running Bosch DME does not affect the timing of the sparkplugs firing. That function is from the flywheel position sensor so the distributor merely provides the mechanical link to conduct the spark from the ignition coil to each spark plug.

[@glennbaz2]

Good detective work. I do think there was an easier way. I would have used a small rubber tube line. With one end in your ear the other holding next to each injector to listen for operational activity. Then just seeing if you have power. If you have power, and no sound, replace the injector. This also works on parking sensors on bumpers. Worked for years on Porsche/Audi in the 70's and learned a lot. Early systems were mechanical injection at over 200psi. Different times for sure.... Keep it up. Glenn

Excellent video. On my ‘94 Carrera the EMS tool allows to diag the injector by pulsing each one 👍. Can initiate test, run around and listen for click click in engine bay. 👍. I probably didn’t need it, but, while engine out, I sent injectors to RC 👍. They are local to me, Looks like you’re getting close 🥳

[@HeidiandFranny]

Thanks! Getting back to it tomorrow :)

[@brucenemerov1403]

A stethoscope is very good to check injectors with. And faster. Just put the probe on each injector while running, and you can hear the clicking of each injector.

[@gregculverwell]

I had an 85 Carrera for 20 years up until 2 years ago when someone offered me silly money for it (I had intended to keep it for the rest of my life) It was the European model, so no cat, more power and a gearbox oil cooler. When I first got it there was also an idle issue, but not the same as yours, but maybe related. Mine would want to stall if you suddenly lifted off @ low rpm. It found that there is an idle airflow adjustment screw (just behind the idle valve if I remember correctly). By turning it out a little I got rid of the problem, but if you turned up its out too far it raised the idle above nominal. My impression is that the idle valve is just fine tuning, cold running and to compensate for the air con.

[@HeidiandFranny]

Yup, you are totally correct. I bet the different fuel here vs Europe was the reason it needed an adjustment. Our car was running fine before so I don't think that is the issue. The manual says it needs to be adjusted with an exhaust gas analyzer. I want to get the injectors all working properly and then verify each component to be sure everything is up to spec.

[@martinfilardi2614]

Wow, great diagnostic algorithm. I have the same car. A common issue with the 3.2 is busted head bolts , which could drop compression but you may see an oil leak. I didn’t know that you could bench test an injector with a small battery. Great video.

WoW! FI is not something I'm familiar with, but you really systematically isolated the faulty component. WoW, great job Franny. IF I had a suggestion, it would be that you secure your lovely ponytail. I was a little frighten to see it moving around so much with the engine on, and the belt right there. I only remember from my H.S. days, (69-73 ~ ancient I know) of a friend that had long hair, and working in the machine shop during class on a lathe, it got caught and pulled his head down right to the machine, and only by yanking his head and pulling the hair right out of his scalp saved him from serious injury. He had past shoulder length hair.... . Anyway, great job, watch out for those purdy locks :-) . So glad you figured it out so methodically. Great video. :-)

[@HeidiandFranny]

Thanks so much. Yes, Heidi had at me with the clippers ;)

[@dudeonbike800]

Awesome problem-solving. It's like you're an engineer or something :) And how nice to be able to identify the problem without having to tear it down much at all. And of course you went from easiest to hardest in identifying the problem, which is obviously the smart way to proceed.

[@HeidiandFranny]

Thanks! :)

At 8:02 if the heads have expanded due to heat, your head to spark plug Tolerance in the threads will be higher in theory. From my experience pulling igniters out of CF-34 engines, it always seemed to be way easier to do when the engine is hot.

[@playitlouder451]

One thought I had was to listen each injector with one of those stethoscope things used for finding noisy bearings. Injectors are quite loud when running at the full 12 V. This would save the work of swapping them around. I never tried this since all my experience with missing cylinders has been with carbs, but I did mess with an injection system for a racing buddy who'd added a turbo to an L Jetronic equipped engine. The injectors on a bench were quite loud without the engine there to drown them out. I've used long screwdrivers in my ear when I didn't have the stethoscope. Works almost as well if the engine isn't too loud.

[@HeidiandFranny]

Thant's a great idea! I really need to pick one of those up. Thanks!

[@gregkillick4261]

A great clearheaded Video thanks so much Heidi/Franny

[@HeidiandFranny]

You bet!

[@TheMattprune]

I dont even have a Porsche but loved watching this, great video. Reminds me of working on 1275 minis...always an issue. Haha. Great content, keep up the great work 👍 👏

[@HeidiandFranny]

I bet the MINIs are fun!

[@TheMattprune]

Franny, Mini's are alot of fun! To drive 😉🤣. British engineering, easy to work on but temptremtal. You should get one

[@lowreedman]

Great diagnosis. I think you are right about the injector having locked up because it sat unused for a year. With such small components inside the unit it doesn't take much corrosion - or even dried oil or something - to cause a mechanical issue. I wonder if the resistance across the connector pins was spec or not. No worries, sounds like RC has your back. Great find!

[@HeidiandFranny]

Thanks! Yup, RC had to work on them a bit and that wasn't the only one... I did check the resistance and it was in spec at close to 3 Ohms. I'm really curious how it will go when they are back in.

[@joanneshellings5457]

First ever excellent explanation of engine parts functioning and testing! Like it!

Hi Heidi and Franny, I watched all of your Carrera 3,2 project movies within the last few hours and I have to say I love it so much. I never saw such nice and experienced people doing this kind of tutorial and explaining movies at such a detailed, charming and entertaining way. To say it in short, you ladies are superb. I am looking forward how you will fix the erratic rough run / stall of your engine. If it’s not the coil (where I could bet it is), it might be a good idea, to double check all the ground points you disconnected for engine removement. I am although interested in, if you replaced the O2 sensor, checked the resistance of cylinder 3 temp sensor even if it’s brand new (and just impacts cold start). And how did you checked for any air leaks (smoke in the inlet manifold)? As said before, I am looking forward to see more of you… Good luck, take care and thank you so much. Cheers Alexander (Germany Stuttgart)

[@HeidiandFranny]

Thanks so much Alexander! I do need to go back and look at all three of those sensors. I have the old ones and they are working (I just replaced them because the wiring is falling apart). I did not replace the O2 sensor. I think I'll do that as well for good measure. I think they are fairly delicate. The ground points have all been cleaned. That is a good call. Thanks!

How did I listen to all that, like I didn't have enough problems to deal with, yes BCS you are an amazing engineer Heidi, and I love Porscha but the beautiful cars Era is over.

[@PatsGarageOnline]

Great troubleshooting process swapping injectors and good test to see if they actually are working.

[@restocal63vw82]

Great informative video and an excellent methodological technique to solving problems . May I also suggest to perform a vacuum test with a pump for all the lines and also a cylinder leak down test. With the above test you shall for sure rectify any snags and get the car running top notch 👏👏👏

[@PhilUKNet]

Great stuff Franny! Your technical skills and diagnostic approach are first class. Thoroughly enjoyable viewing. Was just wondering about your professional background. Care to share?

[@HeidiandFranny]

Thanks Phil, I have a degree in Engineering and have owned several VW Beetles ;) Trial by fire as they say...

[@dudeonbike800]

@@HeidiandFranny awesome! I must admit, I'd be curious to see your resume. Don't really know why, just kinda curious to see the nuts & bolts of your schooling & experience. (Two college and bike racing buddies are Phd's in mechanical engineering and I'm always blown away by their prowess in their respective fields. Another bike guy is an MS mechanical engineer at CERN. And my two college roommates are both university professors in math and materials science. I was not of their abilities, so I like to think I helped with the old "regression toward the mean" phenomenon!!! AKA, the village idiot!)

[@pepperpepperpepper]

@@HeidiandFranny I was thinking either that, or an MD.

[@PhilUKNet]

@@HeidiandFranny The degree in engineering certainly doesn't surprise me! I studied Mechanical and Production Engineering in the UK, but went down the HNC path which has a strong practical as well as theoretical component. Thanks for sharing.

[@stephentempleton9208]

I really appreciate you two- great videos! I have a question and would like your input. I’m building a 3 car garage/guest house that will have in floor piped heating in the garage concrete slab, and I want to have two 4 post lifts in two of the three bays, similar to your set up. My contractor/architect said we could just thicken up the concrete pad, and I think that sounds good- don’t want to compromise the in floor heating piping. Since your in Colorado, not sure if you have in floor heating in your garage and would have an opinion? Also, what kind/brand of lifts do you have, and would you recommend them? How are they secured to the concrete? Thanks again! I’ve learned tons and have applied to my 356C and 912!

[@jamcdona]

I love the way you troubleshoot! Naughty you, keeping them on the shelf that long after cleaning ;) I had mine ready to go in after getting them back, but waiting for 3 or 4 weeks. My Alfa with L-Jet ran like hell and sounded like a VW. I ended up driving it for an hour with Techron in the tank and it cleared up. It's funny- they tell us to install them right away, but we usually don't. Humans, sheesh. BTW, cool to see you wear ratarossa's garb!

[@jamcdona]

I just have to add- those Bosch connectors on the harness side can push back into their housings while removing the harness. This happened to me on the throttle position switch and on one of the coolant temp sensors. Pulled my hair out trying to figure out why it was running so poorly 'all of a sudden'; it just wiggled back into the housing while driving. That one took a few weeks and new parts to figure out...

[@HeidiandFranny]

Thanks!! That's really helpful.. New video tomorrow morning and I did find something, but I'll totally check out the connectors. Wow... That must have been a real thing to figure out!! Awesome work!

[@jamcdona]

@@HeidiandFranny Thanks for saying so. It was a true 'ah-ha' moment when I randomly noticed a pin connector just a bit out of place and not even with the others. I checked all the Bosch connectors I could find and found two. Good news is, you can push it all the way out with patience, bend the little metal tang up, and 'snick' it back into place in the housing.

Never heard before about not removing plugs from a hot engine but makes sense

[@HeidiandFranny]

At least on these air cooled cars there are super hard to get back in... They just want to cross thread every time... Cold they go right in. They are right coming out too.

Great stuff. I cleaned my injectors and The engine now runs better better acceleration esp. in the lo rpm range and sltly lower fuel consumpion according to the onboard meter
