it was pretty easy. when i installed the hose from the bottom all the way to the filter, i noticed on deceleration i was getting a hesitation, like a miss. I drove to dallas on friday and about 1/2 way there the check engine light came on. So after about another hour, i pulled over and moved the hose off to the side a bit instead of directly at the filter. pulled the battery cable, started it up, the check engine light went out and no more hesitation. i guess it was to much direct air.
