I have a 2.2 cavalier that is missing horribly and dies within 10 seconds of starting if i dont play with the throttle this problem just started with the car missing when it warmed up. i have replaced the coil,plugs,wires,injectors, cleaned throttle body new air filter , fuel filter and still no better ive hit a dead end as for what it could be any ideas? :banghead:

Fuel Pressure Regulator? I had a similar problem that turned out to be a pinhole leak in the FPR. Slightly rough but got absolutely nuts when it hit operating temperature.

97 cavalier getting gas; firing turn over but not start.

Then make a thread about it instead of trying to make half-assed hijacks in broken english.

bad ground, clean battery terminals and everyground you can find most notably the one at the starter and clean them with rough sandpaper. and even if that doesn't work which it possibly will it's free.

in this situation it's either a ground or the coilpacks but you've replace them so it's a ground, could be a broken gound wire but probably a corroded connection
