2000+ TJ coil rails
About this time last year I had a post regarding a bad coil rail -- 03 Rubicon.
Symptom was a loss of power, and different temps of the 2 pre-cats.
It took awhile to discover it was the DIS coil rail shorting internally.
It's happened again!
Talked to a guy at CarQuest - he knows what he's doing and a Jeeper himself. He said it's a common failure!
He ordered a new one for me - this time instead of a stock Chrysler one, it's made by Standard Ignition.
I called MSD tech - they don't have anything -- yet.
Has anyone else seen this as a problem, bad coil rails?
They've been using the DIS ignition since 2000 on the 4.0's.
