- After a significant and painful struggle to get the 928 running right - It finally happened! What caused the car to run, but not well for so long?

Congratulations! That's some dedication and persistence.
Thank you!
FYI. Your air filter is upside down. The hump on the filter should be up towards the hood. But, if you have run the engine a significant amount of time and there is contaminants on the top. Don't orient it correctly until you get a new one.
good to know - thanks for the tip
I got my vacuum line online. Paid around $20 for 10 ft. I always replace it ,even if it looks good. Nice job figuring it out.
Online sources are almost always cheaper. I used my local shop and paid the "in stock/while you wait" delivery fee option vs. Waiting for shipping.
I was going to say I got some way cheaper online too, and it was the OEM (I think Continental?) brand braided. I got two sizes to replace all the vacuum hoses on my daily MkIV Golf TDI. Will get the same for my 928.
Glad to see you found the issue. I had a similar issue with my 1985 928. I was pulling my hair out thinking I had a vacuum leak or other issue. It turned out to be the new throttle position sensor cable had two pin switched. Now my 928 runs like a champ. I can sympathize with you on the frustrations and joy on solving problems with these cars. The reward is when you start driving them!!
It is back to running poorly There's another video coming soon on that topic and the fix (again)
Glad you got your issues sorted out though
Glad to see the Porsche running better! And hopefully those night shifts end soon so that u can regain some of that energy back!
Thanks! Nights do end soon, and definitely not soon enough!
nice! You can connect ohmmeter to AFM and read resistance while you manually move that thingy along the contact pad. Resistance should change gradually without jumps. If there are jumps - need to replace the unit. they are not repairable really. You can try to shift (or bend) the contact needle relative to the contact pad where it is not worn. Another thing, there are plenty of european cars from 80s and 90s used this technology and these sensors can be interchangeable. just need to match the resistance range.
I did check the resistance and it seemed to be changing across the meter. I'll get it out under load here soon and see if there are any more issues with the unit
To get your camera to focus up close you need to block the background view. Some put their hand behind the item up close to block the background view. Cheers! 🍻 Great video!
Thanks for the tip - I must have bumped off the autofocus in the camera app settings. I blame my working nights job for the error!
I’m in Seattle with a Mk1 cabby that I am certain to need that vacuum line. Where did you source that from? Look forward to your coming progress!
I got it from the local porsche repair shop, but you can also get it at belmetric.com/hose/
@pharmerthom77 Check FCP Euro, AutohausAZ, Europa Parts. . . to name a few. ContiTech (Continental) OEM braided. Available in 3.5 and 5mm sizes.
Good progress! When are you going back to the Datsun? 😉
Actually working on it right now. Should have a new datsun vid shortly
@@ThrottleGrotto Great! Looking forward to it! Had a beautiful day in the Midwest today so took mine out for a spin.😀
Not meaning to sound harsh, this is purely my lack of knowledge.
But why ( at 8:25 ) is it sounding like ... well ... like a VW van?
Why the clickyclacky?
A few reasons. One, the 928 uses the exact same (l jetronic) injection as a vanagon. Two, the lifters weren't pumped up so they make a little bit of noise at first. And three, the lavalier microphone doesn't have the greatest dynamic range or reach, so the frequencies that it picks up aren't always a full range of audio.
@@ThrottleGrottoGotcha, gotcha ... cheers.
Well, that's unrelated to my VWBus sounding nightmare. A tube popped off on the motorway, and I limped it (with spare oil) to the next junction but before I could get it anywhere useful the thing was sounding MIGHTILY air cooled. 😅
It's still in the shop now, but hoping to get it home soon. 🙏
The US or the German governments fault?
I can neither confirm or deny whose fault it would be
