I have a 94 v6 manual tran camaro. It will start & idle & rev up..but put in gear an dont have enuff power to move car. My repair history to car to date is-fuel pump, fuel filter, plugs&wires, tps,checked all vaccum leaks, fuses. Can any1 help me? OH yeah, it has only strait pipes(had to remove cat & muffler while changing fuel pump)

 

Hopefully you left the O2 sensors in. Is the check engine lamp lit? What transmission are you using?
