cylinder 3 is the middle on the drivers side correct?
Jeep Mechanic: Kavey, Shop Owner replied 1 year ago

Have you smoked it?

Maybe try swapping coil 6 with another cylinder?

coil #6 , it has a wire i thought comming off of coil 5
Customer reply replied 1 year ago
by smoked, do u mean a leak down test or top end cleaning
Jeep Mechanic: Kavey, Shop Owner replied 1 year ago

Coil 6 feeds off the same control circuit as 3. By smoke I mean a smoke tester for leaks to make sure you dont have a vacuum leak.

swap coils 5 and 6 , i do not have a smoke machine but i did spray brake clean around the intake and fuel injectors
Customer reply replied 1 year ago
i meant coil 3 and 5
Jeep Mechanic: Kavey, Shop Owner replied 1 year ago

When you sprayed the brake cleaner were you watching the short term fuel trim?\

No dont swap 3 and 6.. swap another cylinder and 6.. and for good measure swap another cylinder with three too. Get those coils completely off that driver circuit and clear the codes and see if the misfire moves. It could be possible 6 is dragging 3 down or something.

Jeep Mechanic: Kavey, Shop Owner replied 1 year ago

Swap 3 with 1 and 4 with 2.

Ask Your Own Jeep Question
Customer reply replied 1 year ago
there is only 3 coils on this engine
Jeep Mechanic: Kavey, Shop Owner replied 1 year ago

OK then swap the whole coil with one of the other two. Then you can rule out the coil being bad. Its rare for a mopar coil to be bad out of the box but not unheard of.
