Got new plugs three weeks ago - .040 gap. First time I've ever had that issue, and the Jeep wasn't completely cold (I'd driven about a mile & half in heavy stop 'n' go traffic to that point), and it was VERY damp & rainy yesterday. I'm running 89 octane with a Superchips 87 tune, so theres most of the mitigating factors I can think of, for reference.
