Jerky throttle
My car feels jerky (technical term). When I am cruising at a constant speed on level ground the gas feels like it's either OFF or ON. The slightest change of the gas pedal and I feel the car jerk slightly. It's just not smooth. I recently put a new FPD and FPR on. I guess it could also be the something related to removing the UIM during the process. I'm going to try adjusting the throttle cable this weekend, but I doubt that's the problem. ISC? TPS?

It can be done from the commander. You don't need a datalogit.

Try the TPS adjustment. Ive solved many crazy problems on my car and others by adjusment. Its free and easy (if you have a freind help) and quick. A search will help with the tech stuff but if you have Qs or problems PM me Ill give you the #s and locations and the easiest way I have found to do it
