your best bet is to check for codes and get back to us with the results. but if you want i can take a stab at it with the few details and background information you've provided. i'm thinking your timing is off or you're tps is faulty, it's just a guess though so i could be wrong.

It sounds like it could be the tps. did you replace it with a manual sensor? I would recommend getting a manual ecu as well.
