Talking I just replaced my intake manifolds and found this
I had been getting a high idle, unexpected high idle code, and when I installed new manifolds I found the intake gasket on one cylinder had moved to the side 1/32" which was bleeding air into the intake manifold raising idle.

Just FYI if you have high idle issues, there were no other symptons and NO noises to indicate this, was only 50- 100 rpm or so!!

Enjoy, WDY I will try to attach a photo. NOTE the shape of the edge-rounded out
