P0306 on Diagnostic Test

[JeepGuy84]

Driving home, I noticed that my check engine light has illuminated. Before heading home, I just filled up the tank at my nearby Costco. Once home, I decide to run the Jeep diagnostics test and received a "P0306" code. This was last week. Now the Check engine light has turned off and has not illuminated ever since. Anyone know what happened? Should I be worried? :think:

P0306 is a cylinder misfire detected on cylinder #6. It may be an early warning, so keep an eye on it. If you have 30k on your plugs, pull them and get new NGKs in them. When was the last oil change done?

Last oil change was done about a month and a half ago. Not too long ago. Thanks for the reply.:head3:
