: Engine misfires

10-14-09, 07:52 AM
I have 3 codes p0300, p0304, p0306 I think those are the right numbers anyway I have misfires in cylinder's 2 & 6.
My first thought was coil pack. Have others here has issue's with those before? Does anyone know if both coil packs are the same? I was thinking of swapping them and see if the misfires move to different cylinders. I recently changed the Crankshaft position sensor. The coil packs seem fairly simple to remove, I know I could have oil around the spark plugs. so that seems like a good place to start anyway. Anythoughts?
What do you use for spark plugs? It may be a good time to change those also.

I have a 2001 Catera.

I just checked on autozone and it looks like the coil packs are different so that likely will not work to swap them.
