Horrible Start up Driving.

[my98GST]

Is it just my car or does everyone else car drive like crap when you start it and let it warm up for a min or two.

I'm talking about not getting on it but just normal driving shifing at 2800-3k. My car is wanting to jerk, sputter, catch, and a few other undescribeable deals.

Does anyone else's car do this? Its a 98 GST with 147k on the clock. Only mods are fp 17psi wg, stock factory turbo, injen intake.

Does the car run fine after it warms up. Some times in the cold i notice this also. Its because u get head knock. Which caused the ecu to flip out and put the car into limp mode i call it. Until everything warms up. Ive only noticed the problem when it was cold out. maybe this will help u maybe it wont. i dont know anything more of ## problem
