Thread: Engine Misfiring oddly

So yesterday i replaced a bunch of parts on my car. I put in 2 new O2 sensors, a new cat, new plugs and wires, and a new cylinder 1/4 coil pack. After I replaced those I seem to be having some major issues with my engine misfiring. I had a cylinder 4 misfire before which is why i replaced the coil pack. But now whenever I start the car up it sputters alot and whenever i give it gas it will take off, but then immediatly bog down. so its like a constant push and pull when i drive. I had a few codes that i deleted and I drove around for about 20 minutes and i havent gotten any more codes since. Is there anything you guys can think of that could be wrong with it?

Yes. The wires could be in the wrong order. It happens a lot on these cars for some reason. Double and TRIPLE check the firing order. Cylinders 1 3 5 are in the front from left to right, and 2 4 6 are in the back from left to right (left to right as you are standing in front of the bumper).

Other than that could be a bad ICM, bad wiring harness, or cracked spark plug. Also, what type/brand of spark plug did you install? Hopefully either a copper or stock irridium plug and NO platinums...

turned out to be a cracked plug on cylinder 6. thanks for the help!!!!
