Okay my fiero is running great i must say but when i get to 45 mph it takes me a good while to get to 50mph but after that i dont feel any miss or any sudden burst of energy i just see my speedometer going up like it should, so its a rough road to 50 but after im fine? what kind of problem does this sound like?


Thanks, Wes

Not much to go by, but a plugged cat will allow an engine to feel fine until you get the revs up.

Just got my exhaust worked on today nothing wrong down in that area, so im a bit lost myself i have no clue what it could be sorry i cant give me info.

Check your timing. Might be off. That definately affects your acceleration if it's off.
If I remember correctly, with the jumper wire in place on the ECM plug in the console. It should be set to 10 degrees

Okay, when i got it out of the shop he set my timing i would hate to take it up there and ask him to adjust it thinking he did it wrong.

just ask the guy did he a: use the a jumper wire in the aldl link and b: set the timing to 10 degrees.
if the answer is no then it needs to be addressed

I set mine last week and put a thread up at this link with a question (which could relate to your problem if he hasnt done the jumper wire).
