My car jerks a lot first thing in the morning (only in the morning). I had the clutch looked at and their wasn't a problem. It usually when its real cold but it will jerk until it's warm or I'm around 70 mph. I haven't had my fuel filter replaced in a long time. could it be a fuel problem? but again, it only happens first thing in the morning and only if it's cold out.

Hi kravsteve, Welcome to 2carpros and TY for the donation

Jerking, Hesistating and Surging could be caused by the following:

If it doesn't apply disregard it
