Ok so I have a 95 Z24 5 sp that I bought over a year ago as my daily driver, it has 163k miles on it and the guy I bought it from gave me and additional engine cover (with the ignition modules and coils already in it) He said these commonly went out on these cars.
Well last week my car stars missing like crazy and I have very little power on the freeway and manage to limp it home. and I thought why not try to swap those cover and see if that fixes it. So I did and it worked a lot better, not perfect but dramatically better. However I wanted to figure out what part it was that was causing that in case I had to replace it again. So I swapped the coil cover with the coils from the one that worked to the cover with the Ign Mod that wasn't working and installed it on the car. After doing that is was still missing as bad as it was before, so I put everything back where it was, ad re-installed and it worked great again. Is it safe to say the Ignition control module is bad and causing it to miss like that? Based on swapping those out like that doesn't seem like it would be logical to replace the coil cover, and the coils if they work fine on one module but not the other-right?
Thanks for any input or thoughts.
the only way to tell is diagnostic scan. go get it done. could be tons of things.....

I had a huge post in here with problems on that. It can be the module, the white cover itself, the wiring inside, coils, plug boots, springs inside boots,
or in my case the screws that hold the white cover to the metal cover were stripped and let the spark ground out somewhere in there causing codes
and misfire. The platic cover was what mine was several years ago twice, they crack easily. The last time with the screws drove me crazy as I kept
on changing all the parts so I eventually had to pay the dealer $65 to figure it out.
yea ignition on the 2.3/2.4's arent the best. the coil packs consistantly go due to their location on the motor. the heat drastically effects them causing to fail frequently. i replaced 2 in a 6 month period about a year ago. the one i have now seems to be holding up allright . there is a more permenant solution to the problem though. do a search for coil swaps. theres a bunch of ppl running around with 2.2L coil packs wired to the 2.3/2.4 ICM theres even a couple guys who wired up Neon coils. its actually relatively easy, and you can easily upgrade the 2.2 coils to MSD blaster coils. i have a thread saved that has a diagram on how to wire the MSD coils up. basically the same thing.
