Question about 1987 Volkswagen Cabriolet
I pulled my 87 cabriolet out of the garage last spring and tried to start it. It started but ran rough at an idle. I pushed the accelerator to high idle and it sounded like it ran good. When i let off the pedal, it ran rough and stalled out repeatedly. It ran fine when I put it in the garage. I did a tune up and changed the oil. I noticed when I changed the oil that there was a lot of gas in the oil pan. To my knowledge it has a cis-e injection system which I'm not familiar with. What would cause this problem and where would I start to fix it?
I would start with a fuel line psi test. then have your fuel acumulator.
check this out and see if it helps. It sounds like you are priming the psi up when cranking then it can go. but when you let it sit the pressure drops and has to build up again. I a not a VW person myself but love tinkering, so let me know how it goes.

SOURCE: I'm getting fuel to injectors
VOLKSWAGENS THE 1990 MODELS HAS CIS - E FUEL INJECTION. THE FUEL INJECTORS CONTROLLED BY AIR FLOW SENSOR PLATE REST POSITION INCORRECT. INSPECT AIR FLOW SENSOR PLATE REST POSITION. LOW FUEL PRESURE FROM WEAK PUMP WILL CAUSE FUEL INJECTORS NOT TO WORK.
