SES light and missfire

[REDCAM94]

MY 94 3.4 has been a pain. I could never fiqure it out. THe engine misses usually during low rpms and the only way to fix that problem is to accelerate. then the SES light will come on what could it posiible be. I bought a new EGR Change, the plugs and wires were changed 2000 miles ago. Can you please help im taking it for a 900 mile trip tommorow and I want to try to help it so my car wont die on me on the way there.

Try seafoaming it? Sounds like you need a top engine clean.

What about fuel filter and O2 sensors? Set an SES?

Maybe a coil pack starting to go south.

Take it to Autozone and find out what the code is...then you'll know where to start.

It's not fuel, like filter or pump, those get worse will more acceleration not better. My money is on ignition, the scan will tell you which cylinders misfire. If it's a pair of cylinders use the same ignition coil, there's your answer.

well it sounds like alot of people are having this misfiring problem. including me. what is seafoam? ive heard it a few times but dont know what it is.

Seafoam is an engine cleaner. If you do buy it, pour it in very SLOWLY.

If your car is really bad, you should have it professionally cleaned.

Yes, you should have it scanned and find out exactly what code is setting the SES rather than buying new replacement parts hoping to eventually find the problem.
