My friend's 1987 16v GLI is having some problems. The car runs fine, makes good power, etc 90% of the time. However, once in a while it'll randomly lose power and start stumbling and hesitating really badly. If he turns the car off and back on again, the problem goes away. It seems completely random. Any ideas what it might be??? It doesn't seem like there's a vacum leak anywhere...
Only other thing that might be of interest is that the head was off the car this summer because it overheated and trashed a head gasket. The VW dealership he had it done at said the timing belt was off a tooth and they fixed it. Replaced the fan thermoswitch at the same time. And on another note, if anyone wants to trade my clean-ish Audi 5000 turbo quattro for a clean A2 or scirocco, let me know. I want a nice simple, light car for autocrossing and driving to work when my (newer) Jetta GLX is having repairs done to it...the Audi is just too complex to keep around as just my spare car.
