yes, when you oil them and you use too much (it's hard to use the right amount) the oil gets sucked through the fitter and coats your MAF which then gives this code mentioned above, so now you get to find the MAF write up and practice that one, next time when you oil it shake it out a bunch of times to get the excess off, or try not to be such a bro next time and just rock the paper filter like everyone else, lol, j/k and just giving you a hard time, the k&n's are ok but they do have this issue, just watch it next time.


to the op, i see like the others do, vacuum leak>MAF, much more likely to be a vacuum leak in your case, how does your 4wd engage? if it lags it could be from these lines, but really could be coming from anywhere , the propane one is a good one but i prefer to just go over with a flash light and take my time before i start doing things like that, though that does work it does freak me out a bit, i'm just not as manly brian in some cases, lol ;-)
