You don't give any info on a specific problem, so it might be hard for anyone to recommend a course of action. If you want to try spacing the ICM from the head, it will cost you next to nothing as compared to buying a new ICM.

Well from what I've read so far alot of people are running into the same problem, after 20 minutes of running, car gets hot and starts fluttering and hesitating, so I was looking into this fix.

A ground is a ground-as long as it is securely attached and nothing is isolating it from what you are attempting to ground.

Talking Re: ICM- spacers or buy a new one

I had to think a minuite on this post.
ICM
You could have just said "ignition control module".

I have the same problem and have tried a new ICM and spacing the unit off of the head, neither worked. Hope you have better luck!

Re: ICM- spacers or buy a new one

IF the plug that comes off of the ECM into the opti has gray powder in it does that mean theICM is bad or just the wire ????
