Question Higher than normal idle problem

My 1997 900SE turbo idle around 1000 to 1100. It is smooth just seems high. When I put it in drive it wants to go. I need to keep my foot on the brake more than normal. It would idle down the road at around 15 miles an hour or so.
Now to what I have done and checked and it's a long list.
First, I have gone through what I think are all the vacuum hoses. Even sprayed carb cleaner on everything with no idle change. Second, I have cleaned out the butterfly on the throttle as well as the AIC valve. I have checked the oms on the AIC, Crank and boost valve and all are within their limits. If I pinch the hose going to the intake from the PCV check valve(witch is also new and arrow pointing toward the intake) the idle does go down about 100rpm's. Not sure what that means. The motor clunks when I shift into gear, but I know I have a bad right front motor mount and a new one is on the way. The higher than normal idle makes it clunk harder however. I have not taken out the throttle position sensor yet so maybe that has something to do with it. I know the butterfly is closing all the way though.
Any idea's??
