Just a quick off the top of my head description of the hoses.

From the 90' fitting behind and left of the T-stat cover to bottom side of the throttle body directly below the TPS.

Nope. From the 90' fitting, hose goes to to the power steering pump.
From the bottom side of the throttle body goes the 'fat' hose that you see in my photo to the fitting on the top, drivers side of the throttle body.

Bottom of Throttle body (long angled tube) to side of Aux. Air Valve that hangs off front of the intake manifold.

Side of Aux Air Valve (next to previously mentioned hose) to hard pipe thats bolted to the back of the timing cover.

Another fatter hose comes from a 90* fitting on the underside of the intake manifold and connects to the hard pipe at the back of the timing cover. Hose is "U-shaped".

According to connection example #1 above, I think we(you really) have found my the source of my problem.

Comments/thoughts?
