I've got a missfire at various rev ranges, it does it sometimes even on tickover. Having been on a drive, and looking under the bonnet, only 3 of the 4 exhaust manifolds were glowing, we thought that this indicated the problem was on the 3rd cylinder. Do you think that the problem is the coil pack? Can we get this tested or do we need to buy another one? If it was the wastegate actuator it would affect all 4 cylinders we thought?

Anyone, any thoughts please?

Thanks

I have never noticed my exhaust manifold glowing !

Coil packs are known to to break down on evo's, but the first thing to check would be the plugs, take them all out and inspect them all, see if they are all similar in appearence, what plugs are you using, and what power is the car running.

Next is the coil packs, and that is a case of replacing them, 1 at a a time and seeing if the problem goes away
