car is bucking
was coming home from the track the other day and while cruising down the road the car starts bucking then it would run normal for a little then do it again. it did it a while back so i replaced the fuel pump, seemed ok after that till i went to track again.on the way home from track did it again. its not my ignition box because i hooked directly to coil. i replaced coil to eleminate that so im thinkin maybe tps, any other suggestions?

CTS (coolant temp. sensor)
In front, bottom of your water pump.
I am having the exact same symptoms.
Replaced my CTS and it didn't fix. Wiggled the connector and voila....runs perfect (until the next pothole, of course
).
So now, gotta find a replacement connector and get ready for Spring

Am I reading you right that you have bypassed your Ignition Control Module? My car experianced low speed bucking (1st and 2nd gear) about a week before my ICM gave up the ghost.

Echoing Demonic85's sentiment. You are going to replace everything right down to your frame rails before you fix this problem if you're just going to buy random parts one at a time until it goes away. Do thorough inspections and diagnostics until you've found something for certain. Don't just guess.
