Have you tried replacing the ICM?

have you validated wiring and especially connectors are good condition, clean of corrosion, and not busted inside? mine were.. took a dental pick to find out the connector on the harness side split in two and every so often would lose conductivity.

Haven’t had the time to evaluate everything with school, as i’ve hardly been home,
Just had a week for break. Unfortunately the harness is pretty hacked and i feel that it might be the issue at hand. For example, one of the wires plugged into the coil pack was snipped and tied into another wire, which i haven’t had a chance to follow and evaluate, but the car was running fine up until recently. Do i risk putting in a different transistor or is the best case to try and unhack the previous owner’s wiring?

Maybe the bubblegum or whatever he used to keep the wires together is starting to peel apart

Not really sure what he was doing here, any ideas?
