Heres the deal. Bought a 2000 xj 4.0 about a month ago. i put new spark plugs in last thursday and the following day i had a check engine light. got misfire in cyl #3. so i thought well maybe the i had a defective plug so i swapped it for one of the ones that came off it before and same code came back. did some research this morning and found a TSB for this code and the injector heating up and required the install of an insulator. i got one from the dealership put it on same thing, i swapped injector 3 with injector 1 and nothing changed. so my guess is the coil pack? it doesnt look broken, the boots look fine and no other misfires are happening. i tried looking in the dark to see of maybe the spark is grounding out on the head but nope. looks fine to me. so anybody got suggestions before i spend some money on a damn coil pack?
