Gotta love Jeeps with electronic ignition. My 96 Cherokee with 4.0 got to running a bit rough at over 290K miles. I realized the plugs had never been changed. I looked at them, and some of the gaps looked to be nearly a 1/4" !

I recently picked up a really nice '94 Ford F150 with a 300 six. Ran great but just did a good once over as it was new to me. The plugs looked just like that. Worn out to .090+. Truck has 90000 miles, quite sure the plugs had never been changed.
