remove the upper intake manifold (plenum) if your having difficulty taking it off, there are 2 support braces that hold it on, they are located on the backside of the engine, closest to the firewall.... you will have to feel for the bolts, or use a mirror.... i dont remember what size they are, i think they are 13, or 14 mm.... use a short socket and a ratchet.... and dont get aggravated.... they are a pain in the a$$ even for an experienced tech....
