Be careful when tightening the throttle body bolts,as they only go into plastic,and are easy to strip.
If you do strip one,i use ready rod and make a stud .
You probably don't need to remove your intake manifold,but if you do,some de-greaser sprayed inside it,and a run through your local coin-op carwash will hose it out pretty easily,remove the short runner valve before hand on the back of the intake. It also doesn't hurt to spray the heads where the gaskets sit with WD-40,so the O-rings will slide on the surface,and not catch and get pulled out of place.
