Review on ACDelco 25186687 Original Equipment Ignition by Chris Nako

Revainrating 5 out of 5

Fixed my misfire problem

I had intermittent misfires on cylinder #2, mostly at idle. I've seen on the internet how the hard plastic under the rubber boot is becoming brittle and breaking. I installed a new coil pack and it fixed the misfires immediately. Out of curiosity, I cut off the rubber boot on the old #2 coil. Of course, the hard plastic collapsed, allowing the spark to escape. Easy to fix even for a novice mechanic. I recommend this coil pack as it is a GM part and fits perfectly.
