Problem returned
About six months ago I thought I may have solved the problem with my 90 C4 - the engine would die and not hold an idle once "push-started". I think the issue was that my mix would get way too rich due to a faulty head temp sensor and/or 02 sensor, both of which were replaced. Yesterday the problem came back, but it goes away much more quickly than last time - when I take my foot off the gas and let it stall I can restart it and the problem usually goes away. I also notice that I smell a lot more fuel when I start the car in the morning. What else (electrical) effects the fuel mixture?
Also... Today my seatbelt and airbag lights will not go off when the car is on. The airbag light blinks for a split second about 5 seconds the car is started, but doesn't go off. I'm now wondering if my voltage is too low and the DME is unhappy and is causing the fuel problem. The engine turns over immediately though.
Here are some other variables:
My oil was changed recently and they overfilled it. I don't see any smoke at startup so I don't think I'm fouling my plugs. I haven't drained it because I don't think it's too overfilled.
My gas tank was extremely low the night that this happened - warning light was on for 20 miles. Perhaps some tank crud made it through the system - but I still think it's an electrical problem.
Any ideas are appreciated.
