Tested the TFI module?
Pulled the codes?

Tfi

Your ICM is overheating guarnteed. You can do a remote mount that will prevent it in the future. Having the icm mounted on the distributor was one of fords most regretable decisions. I think this forum has a step by step remote mount breakdown.

Oh, where is that, I want to try it.

 

[BlackBII]

All you have to do is mount the TFI elsewhere, then run some wires from the TFI to the dizzy. There are writeups all over the net

 

[adsm08]

I might have to do that. Even if its just for the increased ease of replacement.

Seems like everyone is havin this problem lately, including me. Going to try to get to this weekend. If anybody has a link for the remote placement, it would be greatly appreciated.

Yeah. ICM = Ignition control module

TFI = Thick Film Ignition.
