Rough idle has been my nemesis for months and months. But the last couple weeks I've been getting daily CELS with code P0302, and occasionally P0301/P0304. Meaning: misfire in cyl. #2 (or 1 or 4). Which would be related to a rough idle, you think??

Car burns oil so I figured the plugs were oil-fouled. Figured the #2 cyl had a bad case of oil getting in it. BUT I finally spotted that the #2 ignition wire wasn't snapping firmly into place on the plug tip. So I put in all new wires, and after one more CEL immediately after the change and then a 60 mile drive home, it has a much smoother idle, no more CELs (knock on wood), better power (butt dyno of course) and the jury is still out but I think better mpg.

I've replaced plug wires before on other cars, hoping for improvement of various ills, with never any noticeable improvement. But it does happen, apparently.
