Oh.. BTW check the back of the intake for vacuum leaks also check the pcv grommet inside the filter box. there is also a cap that goes over a outlet on the back of the intake manifold that can get removed when working on the vehicle ... long story short--check all your vacuum lines and intake connections , you may have a vacuum leak.

if you have miss hesitation on tip in you most likely have a bad MAF or poss vacuum leak.
