Maybe plugs and/or wires. How many miles? You the only owner?

I have the 2 door version and at 75k miles idle was horrible until I changed the plugs which were in horrible shape

Turns out #4 was misfiring, Lots of carbon on the plug and the wire looked a bit melted. I'm doing new plugs and wires all around. Norge, funny about the mileage. 74k this week
