Hello,
I have an '84 Audi 4000 1.8L fuel injected car that has "fuel delivery" problems. It will start and drive for up to 5-10 minutes until it starts to loose power, sputter and hesitate and finally stall. While these symptoms are present, trying to use the accelerator actually seems to make the symptoms worse. For example: your stopped at a light and try to accelerate. This is when it will ususally stall out.
My local VW/Audi/BMW mechanic cleaned some gunk out of the fuel pump and I drove the car for 30 minutes until the symptoms returned. My mechanic says that he is not sure what it is and if he starts replacing parts it is going to get expensive. He has "confirmed" that the fuel pump is working at least when idling but not while the car is being driven.
So, if you might have any suggestions to offer or might know someone who knows these cars I'm all ears. Thanks in advance for your attention.
