Default Ignition Control Module for 3800 series 1

I've been told by a mechanic that the '94'* are notorious for going through those modules. I've replaced mine twice within 50k miles. Is he right ? and if so the NAPA store sells 3 different brands. Borg-warner for about $200.00, and 2 lesser brands for about $170.00 and $140.00 Would the borg-warner brand last longer? or what is the life of a typical ignition control module?


P.*. thanks Mike1995, the jumpy tach needle turned out to be a TPS sensor.

I had to replace the ICM in the TGP last year. If it was the original one... It lasted for 20 years.

Heat is the enemy of ICMs. If there is anything you can do to keep the heat away from it you will prolong its longevity.

I have a 95 L27 (series 1 3800) ICM I can sell you cheap if you're interested. Just pulled that engine to get an L67 swap done on the car. Send me a PM if you're interested.

Jon,
You're right those get pretty toasty !! What would be a good way to deflect/dissapate some of that heat?

Some heat reflective tape on the bottom of the icm works best.

Thanks, I'll try the tape. Are the borg-warner brands any better than the others?

No not really, If you can find something cheaper go for it!

You sure you don't want me to send you mine? Engine worked perfectly when it was pulled.
