Re: need help with 2.2 sunfire
Welcome to AF!
I suspect you have a plugged cat that is causing too much back pressure to allow the engine to rev beyond the 2k level. Pull it loose and start the engine with open exhaust. If the car revs, problem solved.

Re: need help with 2.2 sunfire
ok well i think i found the problem when i took the fuel filter off the gas that came out was black looked like coffee so i am goin to drain the tank, clean the lines and get new injectors because the stuff that was run threw them was the worst i ever seen. has anyone ever heard of the o-ring going bad on the injectors on a 2.2? I know on semi trucks they go bad and the oil passes threw and travels back to the tanks. thank you for your help and i am sure i will be back to ask more questions.
