[QUOTE="msgntsu, post: 460849, member: 24156"] I’ve tried to research as much as possible, but really didn’t find anything to help me diagnose my error code. I woke up this morning to an engine idling a little rough (by the way, i didn’t notice the rough idle after driving somewhere - only at cold start) and then my check engine light came on. Checked code to find it was a P306. I researched a little to understand that it was a misfire on cylinder 6. Seems to be a wide range of possible issues, but way too many to just start diving into. The jeep has 98K miles. I changed plugs at 92K (Along with oil cooler filter housing). Based on that it seem unlikely that it would be a bad plug, but I guess that might be an incorrect thought. What is the best way to start trying to locate issue? As most know, it’s not simple to just pull plug on that side. This is also my daily driver, so I need to resolve soon. Also, are there risks with driving it with that code? Thx. [/QUOTE]
