ok, i thought it could be the o2 sensor, so i changed it and it didnt even make the light go off. i have had miss fires and when i press hard on my gas prolly about half way or more the car sounds like it is just miss fireing over and over again, until i let up on the pedel then it runs fine.

another thing i was worried about was that the kid who had the car before me put a ai/ fuel guage in the car and when he did he cut one of the wires that connect to the o2 sensor. i took it off cleaned it and taped it upbut im not sure it it could still be a problem??
