Question about 1990 Volkswagen Cabriolet
Manual Transmission, High pitched humming sound right rear side (passenger), smell of gasoline, the gas cap is not locking all the way, engine needs gas (throttle) to start engine, idles fine upon startup, after engine runs for 1/2 hour engine stalls at stop signs, when hot, car does not idle (stalled) when gas pedal is depressed once running cannot exceed 40 rpms and stalls, car needs to cool down then startup is fine, Car jolts when stalling.
I need help diagnosing this issue, I recently purchased car, I need an emissions test, every time I bring for testing the car will not idle, too hot, I am asuming. I have replaced the fuel filter, oil filter and the air filter, put in new fluids, oil, anti-freeze etc.
Ignition system sounds probable on vhicle when everything gets warmed up. High pitched hum could be bad tire or worse bearing.

Testimonial: "Thank You for your response. The huming sound is present on idle from start-up,tires have just been replaced, would fuel pump be suspect?"
I have a 1990 VW Cabriolet that had the same problem. My mechanic replaced the fuel transfer pump and it fixed the problem with the fuel smell and the noise on rear passenger side. My car still has the low idle problem, but it's not related to the fuel pump. I have to run the air conditioning to keep the idle up when I'm not pressing the gas pedal. I wish I knew how to fix that. Hope this helps! (I found a fuel pump for $20 on ebay, installed by a mechanic, but I just got lucky on the price. Usually they cost much more.)
