only in first gear its as if someone is turning fuel on and off. I put on a 93 cobra tps and the problem is worse. Ive about had it with this piece of ****! Besides this problem car runs PERFECT idles perfect at 750 always. I know its gonna be a guessing game on what to replace first, so Im open to ideas. thanx

 

ignition control module?

 

Have you pulled codes? If so, what are they?
Have you cleaned IAC, MAF, 10-pin connectors?
Checked vacuum?

I would just go through it and check everything you can, and give everything a thorough cleaning..
