For some reason I am having problems with my darn car. The thing keeps stalling every time it gets wet outside. I have no clue as to what is the problem. I have had mechanics look at it but no one can seem to tell me a solution. If you have any suggestions--PLEASE LET ME KNOW!!!!!!!

The car starts fine cold. Use it or let it idle for about 20 mins. then it stalls. When I smell the exhaust it is definatly getting too much gas. I believe it's in "limp in" mode. If you depress the gas pedal it will run but release it and it stalls and won't restart for another 20 mins. Could be heat related but the cooling fan works and there is no overheating occuring. I have changed the ECM, spark module, temp sensor, plugs, igintion wires, throttle module pintel. When ifs on the analyzer it gives every fault code going. It's finally pissed me off enough to consider putting it to pasture except when running it's great.
