My 2000 Wrangler with inline 6 cyl. has a misfire code on cylinders 3 &5. I had a garage replace the coil pack and spark plugs. Code is back ? Injectors ?

Asked by Feb 20, 2017 at 02:42 PM about the 2000 Jeep Wrangler

Question type: Maintenance & Repair

It seems to be running smooth with an occasional drop in rpm at a low rpm.
Nothing alarming tho. Could it be the injectors ???

Did you replace the plug wires?

just the coil pack , which connects directly to the plugs I thought .


I think you are correct. Several different styles came up when I did a search. Is the CEL on? What are the codes?

CEL is on steady, no blinking. He told me the code was a misfire at 3 & 5 cylinder . It runs smooth so he thinks its not the new coil assembly or new plugs .


It might help to know the actual codes.

Not sure . Only told it was misfire at cylinder 3,5. I will try and get a set of rebuilt bosh 4 hole injectors and change them... Worth the try . Thank you ....
