 Loss of power I just feel like recently I have been losing some power. Minor missing during start up as well. Pulled plugs and they seem to have some weird pattern on them. Anyone ever see something like this. Almost seems like some kind of blow by or something.
There is like an oval discoloring on them.

Re: Loss of power Ended up being a dirty MAF sensor. Guy at work used to build foxbodies and he said they are notorious for getting dirty and making an engine run like crap. Sprayed it down and got all my horsepower back. Do need to figure a better intake system. Need to find something with a 90 degree bend to make it a little longer.
