2003 gt

My '03 gt has been thrusting alot in each gear like it doesn't want to move. Had a few people look at it but nobody can tell me what's going on. Any ideas?

Explain thrusting. Auto or manual.

It's jumpy. You push the gas and it acts like it doesn't want to speed up. It's a manual. Does this in every gear.

Yes. Has been for awhile. When I get on the interstate and out it in fifth the CEL will flash for a minute then go back to just being on.

Go to autozone and get them to scan it. Get the code and description. CEL system is a great tool man. If you do a lot of work on your own car, a cheap scanner is a great investment. Let us know the code.

I have done this many times. First thing it told me was an 02 sensor. Replaced it. Still says I need to replace it and 3 other things. I will have to go back to check again. It's just getting old and annoying.

Get them to give you a print out of the codes. Let us know. Just cause it says o2 sensor doesn't mean it's bad.

Yup. 2 actually check the exhaust gasses before the cats. The 2 after the cats only monitor the cats efficiency....troll

Well I just got a new intake manifold put in last summer. So I'm not sure if that's my problem.
