Did the ignition control module coolant temp sensor and plugs last summer. Was getting on the gas a bit today, and the car started missing. I babied it home, and listened to it in the driveway.

I heard it knocking at idle, its rough, and codes were as followed:

16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 35-10 - - - Intermittent
16688 - Cylinder 4 Misfire Detected
P0304 - 35-10 - - - Intermittent
16686 - Cylinder 2 Misfire Detected
P0302 - 35-10 - - - Intermittent
16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 35-00 - -
16688 - Cylinder 4 Misfire Detected
P0304 - 35-00 - -
16685 - Cylinder 1 Misfire Detected
P0301 - 35-10 - - - Intermittent
16685 - Cylinder 1 Misfire Detected
P0301 - 35-00 - -
16687 - Cylinder 3 Misfire Detected
P0303 - 35-10 - - - Intermittent
16686 - Cylinder 2 Misfire Detected
P0302 - 35-00 - -

I just did both motor mounts last week but havent had issues until today.

When I was driving home, the CEL would blink and it would be rough, then stop blinking and it would be fine. The only reason steering me away from the ICM is that its missing on all cylinders, but then again I did replace with the HUCO brand and maybe it failed? I tried moving coils around, and the plugs don't look bad.

Ideas? Thanks!

Got a new one for pretty much cost +tax at the local shop, came out to like 75 bucks, installed it, and seems good. I think this issue had something to do with the thermal paste used that when everything heated up and fried the HUCO. When it started missing at first it was when the car was hot and I was banging through the gears at high RPMs. Used a better paste and we'll see what happens.

I sell Arctic Silver 5 Premium Silver Compound and their ceramic version. It is ideal for proper heat transfer under the worse conditions.
