2000 Chevrolet Cavalier Base 4 Cyl 2.2L


Car runs and then acts like it has jumped timing??

I've replaced the coils, plugs, wires, fuel pump, fuel regulator, O2 sensors. It will start fine and then when warmed up if you press the gas pedal down to far it almost acts like the timing jumped. If you feather the gas pedal it will sometimes work through it but there is no reliability. I've read a "too lean" code from the engine light. When it acts up, you can floor the gas and maybe get to 30mph, with no engine rev or anything other than a jump forward here and there. Please HELP
