Pulled the plugs and found a couple #2,#3 had oil on the plug ceramics. Replaced the valve cover gasket, plug tube gaskets and replaced the oil supply tube seal, it was hard as plastic. Started it after I installed the gaskets and new plugs, ran better yet, but still misses. Flushed cooling system and replaced thermostat while thinking what to do next. I was thinking maybe the water wicked up the plug wire cores, so I replaced them. Ran better but miss is still there. Cleared check engine light, after replacing the gaskets, but came on when I went around the block. P0300 and P0302. Random misfire and misfire on #2 cylinder. Some of the posts I've read seem to recommend cleaning MAF. Could the MAF cause the misfires?
