I changed my spark plugs yesterday and now I have a check engine light. I took it to AutoZone and they scanned it and came up with a cylinder 2 misfire. I put on new wires and put a new plug in cylinder 2. I'm still seeing the check engine light. Any ideas? Here is a picture of the the spark plug I took out of cylinder 2 . 2 and 4 looked like this but the rest looked normal . I have 78270 miles on this 2011 JK.

Which plugs did you replace with and did you gap them properly prior to install?

Did the plugs look like that before or after you replaced the wires and which wires did you replace with?
