Re: ICM and Coil...

If any of these two are bad, or malfunctioning, can this cause detonation problems on cylnders? For instance, some cylinders not firing correctly?

Re: ICM and Coil...

it would be random missfiring. If it is the same cylinders every time, its prolly either a wire, plug, or the opti.

The coil is bolted to it. There will also be a stud on the head that has a bunch of grounding wires, that stud is also holding it on to the head.
Tons of deposits in the head and/or pistons can cause detonation or possibly a malfunctioning knock sensor, try a little sea foam to clean out the engine. Does it throw any codes?
