Angry #3 Cylinder Coil Pack Keeps Dying

I have a 94 WRX, with the Coil pack conversion.(approx 3 months ago) last week #3 died. I replaced the coil pack and It lasted about 3 days, now its dead again. Is this just a case of bad luck or is there something else I should be checking before I replace it again.

I had this problem, are you doing the conversion yourself? Key thing is, make SURE you have an acceptable ground. If the coil is not grounded properly, it will inevitability fail. It took me 3 different coil packs to find this simple solution. other than that, make sure you are using a non-conductive epoxy when you epoxy your wires. Hope this helps.

I appear to have the same problem. I had a bad coil pack, unrelated to the coil mod with completely different symptomes and obviously damaged from being dropped, so I decided to replace all 4 with new packs. Now the car acts like its running on 3 cylinders.

It only happens when the car is at operating temps and it is intermittent. This happened right after replacing the coil packs so everything was unplugged / unbolted and resecured...no issues for a few days, then the problem started again.

I've narrowed it down to #1 and / or #3 by unplugging the injector clips to see if there was a change in the idle.

I removed the paint on the coil pack to assure a good ground but no luck. My question is, can I use a different grounding point on the block or do I have to ground to the coil pack?
