Okay, little more info...replaced the plugs today and changed the gap. It was previously set at .035 and I increased it to .045 per a thread by Warmonger I believe. Still have a misfire I think, need to take it for a drive...but the wires are still stockers, only 38k on them though.

Plug gap



Hate to say it, but 38K miles is almost exactly what I had on my stock wires when they were completely crapped out! Hate them...change them....burn them....
If you have stock wires and they aren't new as in less than 12months or 12K miles, then suspect them too.

You may be getting misfires from it being lean as you have already suggested, but wires are a cheap check and with 38K on them I'd dump them in a heartbeat.
