ok i have just bought a silver contour svt with only 34k miles on it. about 2 wks after i got it the check engine light came on after i did a burn out. eversince then the car seems to studder when im hard on the throttle mainly in second and third above 4k rpm. it doesn't do it all the time but most of the time. i don't know what the problem is but can anyone give me some advice on what to do please.
