i was cleaning my lumina out one day when it starting idleing rough so i taped the gas and it shut off the batt. drained and was time for a new one anyway so i baught a new new installed. the engine turns over now but when i touch the gas to much its shuts off and to little and it shuts off maybe someone can help me before i bring it to the shop. thanks:disappoin

What year car, does it start right back up, need more info here! What does and "too little mean"?

ok its a 93 lumina 3.1 70k have'nt had any major problems before.

I meant that i have to push the pedal a little bit if i push it to much it will also cause it to turn off. Iam thinking that it could be a fuel injector problem but iam not sure.

check your fuel pressure, it should be in the range of 44 -47 lbs.. if it's lower than that have your fuel pump checked..

The throttle position sensor could be giving fits, also.

ok iam going to have to wait till the morning to do check those things thanks for the help ill tell yas how it goes.

So it turns out that i have a bad fuel pump they want 350-400 to replace it guess i gotta pay. i heard its a pain the ass to do that job myself

I'm not sure about the older body lumina's, but the newer body one's are a piece of cake to swap.

The 93 model has to have the tank dropped to change the fuel pump. It doesn't have the access door in the trunk like newer W-bodies.
