2004 Chevy Cavalier Trouble, please help!?
Hello. I have a 2004 Chevy Cavalier that has been acting up lately. It has been misfiring on and off. I took it in to the mechanic who said it was the coil pack. I found this odd as I had that replaced back in February. Anyway, I paid him to fix it, picked up the car, and started driving down the road. I got all of about two miles when the car was misfiring like crazy. I brought it right back to him. He hooked it up to the computer and said that it was water on the engine. He said if I just rev the engine in neutral at about 30 miles an hour when it's doing this, it'll clear up the misfiring. He said it could also be the sparkplugs. Now, I'm certainly no mechanic but this all sounds a little strange to me. At this point the check engine light is on and I'm getting misfires pretty regularly. The misfires are generally small ones and the car is managing down the road just fine. It's unlikely to be a transmission problem as I drive a standard. The oil was changed in the last 2 weeks as well with no concerns there. Any ideas?
I suppose I used poor wording... When I said down the road I did not mean downhill, I meant simply putting my foot on the pedal and accelerating forward.

The car has a Quad 4 motor with 4 coil packs they can go bad if not grounded properly . The computer can not tell that water is getting in the engine . Look it the dip stick and see if water is in the oil, it will be a little milky if it is . You might need to have a compression check done to see if you have a bad head gasket ! This can cause a missfire code !

Hello Robert. Hyper is correct. Have someone strike the fuel tank with a rubber mallet while you crank the engine. If the vehicle starts, get it to a reputable shop for proper diagnosis. Of course, if this procedure works, you definitely need to replace the fuel pump. Peace.

Sounds like the fuel injectors are clogged. Those fuel injectors are prone to clogging and there is a TSB addressing that issue (TSB 030604030). If the mechanic you took it to didn't suspect a fuel injector problem then you need to find a better mechanic.

You say down hill is OK. I have a suspicion that it is the in-line fuel filter. Also, you might have got some bad gasoline. Run the to almost empty underline almost. Get some fuel treatment and fill it up. Try and get your gas at one place. Going here and there to and fro no telling what you picked up in your gas. Try and commit to one station.
