do my plugs looks ok?
what are you gapping them at? that looks larger than .045". if it really is a lean mixture, look down the sparkplug holes without the sparkplugs and see if there is a lot of dirt down there. if they're not seated properly, you may be sucking air through the tiny openings. make sure everything is on right even if it means taking it off and putting it back on, just to know for sure.
the coil pack thing could happen. i've heard of them having to be replaced. but it's not common. the coil packs are those things that go over your sparkplugs.
not too sure if the PB would be the problem. people who usually had problems just had bad splicing skills.

From: ill be home soon
well i changed out the plugs yesterday and gapped them at 41...i didnt check what the stocks were gapped at.......coil=spark plug wires? or no? what do i do if there is dirt down there?
gap is supposed to be .039-.043. oh yeah, mine are actually set to .044 because my gapper doesn't have .043 and .040 was giving me problems. i have magnecors also and no problems from me.
oh yeah. brand seems to matter. make sure you have ngk, champion, or denso as those are oem manufacturers for mitsubishi. ALSO make sure that if you have platinum sparkplugs, that they're double platinum and not single platinum. single platinum sparkplugs can work against themselves on waste-spark ignition systems.

If your car was misfiring that could very well be why the one looks burned on the ceramic and whitish on the tip. If for some reason your ignition timing is off (too advanced) or you're knocking for some other reason, you really should just take the car to the dealership. May wanna swap the stock plug wires back on before you do that though.
I haven't had any luck with Platinum OR Iridium plugs. Mine all fouled super quickly. Both NGK and Denso.
BTW, now that the pics are in a line you can actually SEE the clear one.

Umm im pretty sure theyre supposed to be gapped at .028-.030 as the service evo manual states.. that might be one of your misfire problems. I gap mine at .030 and have had no problems.. no misfires.. nothing runs to redline perfectly
hey i have a question i checked my stock spark plugs and all my plugs are all burnt almost black all over them in the bottom and when i look down looks like i have dirt in there what does this mean ?? i just ordered bpr7es plugs i have 19,000 miles on my car also and this goes for all spark plugs and holes
