Just got a FRI Littleboy cam istalled and picked up the truck on saturday. Sunday I went to the track and during a run my check engine light went on(ran slower with the cam then without but havent got logs to JB for a revision yet). two codes showed up on the predator. P0441-evaporative emission system incorrect purge flow and P0300 random misfire detected. P0441 also came up a couple of weeks ago after my headers were installed. I was reading another thread and it said it could be a spark plug issue, mine were changed with the cam install. can someone tell me if this is a serious problem and/or what to do.
