Question about 1989 Volkswagen Cabriolet
My 1989 Cabriolet has a fuel delivery problem hat the mechanic can't figure out. He's been through everything obvious and not obvious he knows but the problem persist. The car will start, then run fine, then sputter like it is about to die or does die. Then it will run great for a few miles then it happens again and again. Then it won't start for a while, finally start and do it all over again. Can anyone point to something we're missing? Thank you so much. I need this car to run! Help please!
Mine was doing that, I checked carefully and found out the fuel accumulator was leaking especially at higher RPM's which starved the engine of proper fuel pressure causing it to idle up and down, change idle speeds, and sometimes just die. If your car starts up fine when cold and then shuts off until has warmed up, idles rough cold, and seems to lose power slowly then get it back when you give it gas, check the fuel accumulator. It is located beside the fuel pump, under the car body, right under where the rear passenger seat is and looks like an old ignition coil with two metal pipes going into it. There is a rivet type thing on the rear of the accumulator that tends to leak when it gets older. The leak does not allow the accumulator to store the pressure needed for cold starts and high RPM's. Rub your finger over the accumulator and check for any signs of gasoline leakage and if so, replace it.
My gas mileage was also at 17 MPG city which was because the accumulator was leaking all the time. When I replaced it I got 27 MPG in the city.

Yes,it's your computer module
it's dying or so.
it's the one cutting off the fuel system
i've seen that more than once
the fixer it's to replace the module.
but first to be sure.
unplug it for about 10 minutes.
then plug it back on
and test it and see what happens, if it runs fine for a while then definetly that's your problem.
or have your computer checked.
