i plan on removing the walls in the upper plenum in two weeks ,how do i take it off is it difficult.is there any gaskets i need to replace when i remove the plenum.thanks

 

I had to remove my Plenium today to work on my EGR problem. It's quite easy to remove, more than it looked like. As a suggestion if I may. If you have thought about doing the IAC relocating,AFPR,TB Bypass or Porting your Plentium then is the time to do it since you'll already have everything off. All you'll need is Runner Gaskets if you decide not to remove the Throttle Body like I did. Also it would be a good idea to clean the IAC while you'll have the intake out because it gets corroded in carbon buildup unless you relocate it. Mine was really back. But don't sweat it's not bad, I thought it was fun. But I'm weird anyway. Goodluck!

You relocate the MAT (manifold air temp) sensor or IAT (inlet air temp) sensor. You cannot relocate the IAC (idle air control).
But you should clean the IAC while you have it off.

where is my iac if i am to clean it and what does it look like.if i take off the throttle and remove the walls past the throttle body,do i need a gasket for the throttle body

 

the IAC is under the throttle position sensor(TPS) on the left side of the throttle body. I think that you would need a new gasket.
