I took my ICM to O'Reillys not sure if there is one near you but they can check them.

Thanks for the site.Very helpful.I checked for power to the ICM and it was good then I checked the coil with the ICM hooked up and it was good so I'm ripping out the opti.Any suggestions on a different ign. system? cuz opti sucks.Thanks again.

 

Befor you put the new opti on,take it apart and loctite the rotor screws and put some silicone where the opti where it gose together. I done and knock on wood I havent had any problems yet.

 

Yeah I did that about six months ago.This time I think the opti's done fore. Thanks for the input though.Oh and I bought a ICM before I got that thread to the sight on how to test it so now I'm stuck with it.It keeps gettin better and better.But at least the Birds runnin strong.(Knock on wood)Thanks again.
