I have an 89 LE. either the ign module or the coilpack is bad cuz it misses and the bottom left terminal doesn't ground to the screw when i remove the spark plug wire. would a miss cause the check engine light to come on? cuz mine doesn't

Why dont you * tart off by checking code with paperclip and post code on here

The procedure for checking codes is in the techinfo area that can be found from the link at the top of the page.

After that..do you have the original Magnavox one big coilpack ignition or have you upgraded to the next version?

If you are having issues and prove it out, it is probably your most cost effective way. Actaully I can guarantee it'* cost effective for you.

Problem (coil pack) or not still worth upgrading and im sure Bill can help out , he has some mint coil packs for sale.

no no no... i know its either the pack (magnavox) or the module. I'm going to have the module tested at work (adv auto prts)

my question was... would a miss like this cause the check engine light to come on? because if it should, it doesn't.

what was that about upgrading from the single magnavox pack?

There is an upgrade that can be done on yoru igntion system. It was known that the magnavox setup was weak and vunerable at best. You can swap the newer style ICM/coils onto your car if you pick up a mounting plate, ICM and 3 coils. This upgrade throws a better spark and improves mileage/performance from what I have heard.

ya it tested bad after 13 tests, i did that cuz it ran fine til it reached op temp. thanks for the help. i'm still gonna replace the coil pack tho... it looks old, lol

i rly hate those ECM'*. i upgraded to the bonneville from a 87 cutlass ciera with a 2.8, i hated that ECM, i guess that one'* pretty much the same
