Nothing like a new set of spark plugs and a fresh coil (of the correct type) :/
Long time ago I had a jeep dealer do some work because I didn't have the time. They replaced the coil but had to "trim" the connector to make it fit. Ok.. that set a flag, but it worked and at the time that's all that mattered.
Just picked up a replacement from NAPA. Yea, NAPA. :P IC409 to be precise. It's the same vendor as OEM and with the good ol jobber discount, a heck of a lot more reasonable.
Same part number/mfg stamp as the OEM coil that first went out after eight years of service, and the almost
2ft extension harness. (I wonder how much 2ft more run to the coil affects timing?) Anyhoo, now it starts with the first flick of the ignition and runs sooooo much smooooother.
Didn't do a write-up, too easy. But here is a piccy of the part.

It even came with a new connector end to fix the "trimmed" one they left me with. I'm saving it for later.
