Need help: 1988 olds 2.8 V6 ICM failures
 

Has anyone had experience with this engine? Its in our 1988 Olds Cutlass Ciera, and it keeps blowing ignition control modules. Dad just put the seventh ICM in it in the last three years. We've replaced the coils and crank sensor, and we we've tried the normal tricks of using contact cleaner and di-electric grease on it. I hate to ask here, but we're out of ideas.

This can go in the Your Other Rides section, if you'd like to move it.

If no one can help you here, check out www.a-body.net I was a member there since 2003, and there are a lot of helpful people. I believe Don is signed up over there also.

is there corrosion between the icm and the bracket?

or would corrosion on the sensor grounds cause the icm to fail?

did the ciera's have the single solid coil? if so, maybe an upgrade to the 3 coil.

i can never remember, but i think 3 coil= type2 and is that magnavox, or delco type?

www.60degreev6.com is also a great source for troubles with that engine.

Thanks for the pointers...i'll try those two forums.

Its got three coils just like ours.

Here's the thread over there. This car is a clusterf***

uhh, im a lil lost on this advice, thats what plug wires are supposed to do. well at the plugs anyway. why would that kill the icm?

what about corrosion between the plate and the block? if none between icm and bracket

It may help you to clean the ICM plate, coat it with dilectric grease, then install the ICM. The ICM grounds through the plate, so doing that may help considerably.

In my research on doing the OBD2 conversion, GM started using the unused pin on the ICM for a ground lead that goes to the ground junction under the ICM plate. No other modifications to the ICM were done. Maybe adding a ground strap to your setup will help you out as well.

That's what i said we did in the first post.
