Yes, it is a '90 Cougar XR-7, same as S/C. Don't even know what a DIS is. Here arethe symptoms. Every once and awhile it will start to run rough, I would say misfiring. The tachometer goes dead. If I pull over to the side ofthe road, trun it off and restart, everything is fine for a while. When cold, it starts right up. Hot it can take 3-4 tries to start.since it's running rough its a bad DIS module, must be 89-93 supercoupe
94-95 has edis and doesn't encounter that problem, ford did do something right
Which aint gonna fix a damaged DIS, if that's what it is and hard starting says it might be. And "Artic Silver heatsink coumpound" is overkill, but wth..Remove DIS clean heatsink mount and back of DIS apply Artic Silver heatsink coumpound and reinstall . Best place I have found to get Artic Silver is computer shop .
You dont own a SC, so how would you know what the common remidies are ?????Which aint gonna fix a damaged DIS, if that's what it is and hard starting says it might be. And "Artic Silver heatsink coumpound" is overkill, but wth..
A 1990 3.8L does have a distributor and does NOT have DIS.Hi Faust-
I just went trough the same exact issues & symptoms. The DIS is Distributorless Ignition System. I replaced the ICM (ign control mod) for $130 and still had the problem. Next I bought a cam position sensor from autozone for $38 and that did it. The cam position sensor is right under the blower snout just to the pass side. I'd try just the cam sensor before dropping $130 on the ICM.
I'm willing to bet that'll solve your problem.
