Default ICM swap?

I've tried nearly everything to fix my intermitant miss, most things have improved in one area or another. But the miss persists. I haven't tried swapping the ICM from my 93 SE parts car. I see they are different part numbers, but that doesn't always mean incompatible. Does anyone know for sure?

I am also starting to think it may be tranny related.

If its the same year and model and trim level you should be ok....the calibration is probably different though....

i thought that all ICM late 92 93-94 would work. there might be a difference between the SC and the NA coils, but they should work

The coils are the same. I'm already using those. I'm just not sure about the module.

According to Hollander 92 and up 3800 Ignition Control Modules are interchangeable.
