Engine Random Misfire?

1997 Chevy Cavalier 4 cyl Two Wheel Drive Automatic

When I got my car I had my boyfriend change the fuel filter and he did the spark plugs and wires and cleaned the censor. My ETS off light and enigine lights are on and my boyfriend says I have a misfire because when im at a stop my idle jumps a little bit and it sits really low at about 3 or 4 and when I press on the gas it hesitates, also when I sit thru a red light or in a drive thru for about 3-5 minutes when I go to press on the gas it stalls on me but then it starts right back up. My boyfriend says I need to replace the ignition coil, is this the problem?

Engine Mechanical problem
1997 Chevy Cavalier 4 cyl Front Wheel Drive Automatic

I took my car to aamco and they ran a diagnostic test and they said the engine had a random misfire, the car runs but it idles rough and now starts to smoke when starting up

Engine won't idle donw running at 100 rpm's, engine jerks when put in gear. Initially thought it was the motor mounts, changed three of four mounts. When car first starts it runs slower, but all other times runs fast, and jerks when put in grear. Engine check light is also on. Can I do a self check on the ECM, I heard you can retrieve the trouble codes, thanks, I also changed the A-frame bushings.

My 1996 Chevy Cavalier is running VERY sluggish. I took it to Auto Zone and had it hooked up to the computer and it reads cylinder 3 misfire. So.I had the spark plugs and wires replaced. Didn't help. I took it back up there, cleared the codes out, hooked it back up and its still reading cylinder 3 misfire. HELP! What could be the problem?

My car just kicked real hard on me last night while driving, I pulled over and it was knocking hard like a misfire, the check engine light came on and the exhaust smells like a firecracker went off. I just changed all the spark plugs and that did nothing. Checked all the fluids and I am good. I have no idea what is wrong. Can you help me out?

I ran a scan and it says a dead cylinder, I have bought new sparks and had a diagnostics ran to see if the coils were the problem and they are fine also. I checked the fuel injector on top of that and its good too. I cannot figure this problem out for the life of me.

The problem started off like the engine was going to die. If you would pump the gas it would catch back up and go on. Replaced the fuel filter, filter was real dirity. After a few days it got worst, it acted like it was starving for gas or oxygen, then it got where it would barely run. Took out the catyl. Converter and it seemed to have its orginal power back. Did good for about 35 miles then it went back to missing and then it started backfireing. Backfired so bad it busted the muffler. Ran the codes and we replace the fuel pump, camshaft sensor and crankshaft sensor. Ran better but engine light came back on then it acted like the engine was going to die, I kept my foot on the gas and it backfired, it did this one more time within about 3 miles, this time I took my foot off of the gas it didn't backfire but when it reached 20-30 miles an hour I gave it a little gas and it ran good for about 30 miles. The next day I took it to have the codes run and the car started acting like before barely running, missing, sputtering, and backfireing. The codes said camshaft sensor and crankshaft sensor. We just put new ones on could these be bad? Also some problem with the fuel had to cause the cayt. Converter to go bad. I belived the fuel was to lean, thus melting the insides of the converter. Don't know what else to do please help, almost out of money and no car.

My 96 cavalier is doing the same thing, the muffler exsploded and it back fires and it dies on me. I replaced the coilpack and camshaft sensor and cleaned air intake. I been to two garages and they cant figure it out, and it still shows check engine. It is still coding cam sensor. It starts and runs alittle then backfires and trys to shut off or just quits while driving put starts right up. Please let me know what you find out

Found the problem, after replacing the ignition mod. And that did not fix it. We replace the computer and that done the job.

Caronly fires on 2 cilinders. Alredy changed one coil pack on cilinders that dont fire also replaced pluge wires.

First and last on block. Both wires wernt to same coil. Could it be o2 sensor
