hesitation

[AsanBBoy]

My car has been broken for over a month and it sat. I recently replaced a stock flywheel and it now can drive. Durring the down time the car has gained a kocking problem. Now when I accelerate the car, it will hesitate. I can get barely get pass 40mph and it doesn't go above 2k rpms. Any ideas of what could be wrong is helpful.

I'll check tommorow, but the exhaust does smell unusually bad

check ut timing....i had a similar prob of hesitation, running rich, and would not rev over 4 grand. Turned out to be timing.

If it doesnt go above 2000 rpms it is probably the ECU limiting your revs because someting important is broken / not hooked up. Check your ECU codes. If you dont know how, check the faq or do a search.

alright i got this resolved already by playing with the intake and something else, but now i'm yet at the problem i was at before bolt came loose from torque converter or flywheel again (grinding sound makes me ). damn transmission problems. torque specs for them is all i need. i miss driving my car

I had hesitation also and it turned out to be a bad EGR valve but that doesnt sound like your situation ... to test just take the vaccuum line off the top and put a screw in it and take for a test run.
