i have a 2001 cavalier i just traded akid for and it has a lot of shit done to it but i need to find someone who knows about these cars so i can find out why it runs like shit half the time , but it really only runs like shit when u first start it up ,i know the 02 sensor is bad but could that really be all that it is and the car is turbo hello is anyone going to reply?

 

Describe "running like shit" a little better. I used to have one, a couple yrs older. It had a vacuum leak one time and that made it run real rough.
