Well I. Thought I had a spark issue and why I'm getting my random misfire code. But last night my buddy that's a gm tech came over with his fancy 4 grand scan tool thing. And plugged it up. He was able to get more codes then I could emagine. I have a random misfire p0300, a p0171,p2119. There were more but that's all I wrote ddown I know one is a thermostat code.another is a lean code. He said the car is staying in open loop and won't close and with his computer he couldn't even force it to close. He said that could be because of the thermostat not letting the car get up to temp or get to temp fast enough^taking too long and that could be the issue (I have noticed doing 15 min of city driving on cold 45 degree night my car only gets up to about 145 to 150)but he also said only cyl 2 and 3 are miss firing pretty bad. And that its on start up and idel. I'm not getting enough fuel so then the car starts dumping fuel in there to compensate and even it out and then its too rich. This is alll fixed when giving it gas for the most part the problems go aay but not totally. He said my long term fuel trim isis veryyyyy rich. Can someone pleasse help as I need to get my echeck in a week and the car will fail how it is right now. I contaacted my local tuner to get ahold of vince but like always that guy is more busy then the president of the usa I guess because he never gets back to you after he has your money. Thanks chris
