Blown,

I just got off the phone with the mech who modded my engine and I have an answer to the mystery. Apparently, there was an "air flow divider plate" that he fabbed and installed at that location. The flow plate is supposed to divide the air flow more evenly or possibly to increase flow to both sides of the intake manifold resulting in a HP boost. The plate had bolt holes that were threaded and apparently at least one of the bolts backed out and the other one let go for some reason (he used loctite) resulting in the divider plate letting loose and sliding somewhere inside the manifold which is where it is now.

I understand the plate is too big to fall into the intake ports, but it may be now hindering air flow to one bank of cylinders. Now I just have to figure out how to get that thing out and decide if I want to reinstall or not!

Now maybe THAT was the reason I suddenly started having cold idle issues and intermittant warm idle issues just recently!

HOLY BLOCKED INTAKE RUNNERS BATMAN!!
