removed the eight runner to plenum bolts. But plenum is stuck can't even wiggle it around. What am I missing here? Thanks for the help.

 

There must be a bolt you havent got yet check in between the runners for them bolts........ remove all the vacuum lines........ if that doesnt fix it it is just stuck on the gasket SOOOOOO WHACK THAT BIATCH WITH A RUBBER MALLET WHACK THAT BIATCH WITH A RUBBER MALLET

 

I just took my plenum off about a month back and you need to loosen about half way out the 8 bolts at the bottom of the runners and then make sure eveything is disconnected from the plenum then just wiggle it and its off.
