So today I was taking a turn at normal speed and little acceleration when my VSA light went off for no reason and the car began to jerk strangly....I exited the turn and VSA went off and things were ok for like 3 seconds and then the car began to jerk again....I couldnt tell if the tranny was slipping spuratically or the engine was putting.....any thoughts???? There was also a weird smell like something burned afterwards....

Thanks....
The only other weird thing is that my car had trouble starting the other day....It turned over but wouldnt start.....I went to the gas cap and tightened it, as i found it to be a little loose....Then it started right up....

Only mod is CAI
