Camaro Misfire help

[Dekay]

Hey guys,

need some help! My car ('99 camaro)is misfiring. I don't feel the misfire itself but the computer is registering a misfire on # 1 & 3 cylinders. The car just had new plugs, wires & ignition coils put in and I was hoping that would have fixed this. I drove it for about 50 miles since all of the above was done and the service engine light came right back on.

I did a search on here and the only thing I haven't done is replace the fuel filter. Would that really cause a misfire? Who makes a good quality fuel filter and how much do they go for?

If you guys can come up with some other ideas as to what I should check, please let me know!

Thanks!

I suspect that a general fuel delivery problem (bad fuel filter) would not cause a cylinder specific misfire. What i mean is that if a bad fuel filter could cause a miss fire, then it would be randomly to any/all cylinders. Not just 1 & 3. I fought with a missfire problem for months. It can be be something as simple as the wire boots not fully seating on the plug or coil posts. Double check to make sure all of the plug wires are fully seated on each plug and coil post. Use dielectric grease(dab only) on the plug wires.

It's probably your coil because it's getting a misfire in both cylinders.

Well... last time it happened to me because of burned wires... but it could be anything with the ignition... just check wires, boots, coil... it's probably a very small problem.

Hello, I just went through this similiar problem and 800.00 later I found out that it was the sensor that tells the ignition module when to fire, this sensor is located behind the flywheel and costs about 50.00. If you are mechanical with the right tools then it is an easy fix. The coil packs are able to be removed and any competent electrical shop would be able to tell you if they were bad.
