im getting a code for cylinders 1 & 2 misfiring. I have perfect oil pressure and a steady 200 degrees on the temp. The current thought is the coil pack, however they are not known for going bad. I havent taken anything apart yet just looking for some ideas if anyone else has had this issue.

 

no smoke, loss of power or noises either.

 

Pull your plugs and see what they look like. Start the Jeep in the dark and look for spark. Make sure your injectors are working properly, and also check the crank position sensor. Keep us updated!

 

pulled the plugs the dark one was finger loose.

 

I don't think your motor came with those plugs.. Get a set of champion's and turn of the mil and see if it comes back after 60 miles or so. Only reason I go with Champs is because it's recomended from the factory.

 

yup Pitch the Bosch E2's and get standard Champions........then try again.

 

Other than the fouled plug, they look good. I agree with the above posters - get Champion plugs and try those out. Good luck and keep us updated!

 

i cleaned up the plugs and reinstalled them and no light with a better sounding engine. i will still replace them with champions this week.

 

Cap & rotor could be suspect as well.. I just has a #1 misfire intermittently & found it was arcing inside the cap.. nice lil' carbon trail coming down from the arc terminal.

 

Alright, that's great news! I would replace them too. I'm actually going to relpace mine because Autolites are in there now...bleh...

 

its the coil pack i had a miss fire on 3 and 6and when i changed out the pack it fixed the problem. sometimes you get a lemon and you will have some problems

 

no cap and rotor just coil pack.

 

put some miles on it today and no light, looks like the #1 cylinder was the plug that wasn't screwed in completely and #2 cylinder was the plug that had carbon buildup.
