I have had this problem for a while and it quite annoying did all the regular steps and it is now intermittent. My system is supercharged though so it is more complicated, I believe it has an oil based k and n filter. Should I try a dry based one on the list of possible problems? Am also looking into getting a smoke test for any vacuum leaks I am not able to spot.
