I'm chasing down a random high rpm miss etc, i was messing around checking connections and noticed my coil rocks in the mounts that it sits in.. The metal bracket is stationary, but the coil itself is able to move... I also noticed i could see some spark around it the other night, when i revved it, it would go away..

 

Your coil should NOT move.

When you get a new coil, you'll need to break off the rivits that hold it to the bracket. Quite simple. Take a flat head screwdriver and smack down on the protruding side of the rivet, and it will break off. You can then push it through the bracket.

A new coil will have small bolts to use.

 

thats what i was figuring.. This is an msd that's only been on the car since november...... wonder why the heck it can rock in the mounting plate??

 

My experience has been that MSD coils cause problems. Go back to stock.

 

same thing i noticed also, but when the motor came back from the builder last time, it was on there.. I was sort of hmm i didn't put that there, but didn't have a stocker to replace it with..

 

Your GM dealer does... for $15.

 

thanks i'm going to order one up this week, and see if it helps out any..

 

When you take your coil off, you'll notice the bolt on the driver's most side has a bunch of wires connected to it. One of these is one of your ground straps. You can follow this wire down to the strut tower of the car. Make sure this wire is in good shape. If its not replace it with a 10 gauge wire and make sure all terminals are clean.

Always use some of that white heat transfer grease to the back of the bracket
