Idle Speed After Installing New Supercharge Wheel
This is gonna be a dumb question, but here goes. I changed from a stock wheel to a green wheel (Riva Stage 2) in my 04 RXP. I didn't change any of the throttle body settings after the rebuild, because the manual says that the idle speed it not settable and is maintained by the ECM.
IDLE SPEED (this is from the service manual for '05)The idle speed is not adjustable. The ECM controls the idle speed of the engine.
I think I should adjust the idle speed because I was way high on the trailer and almost uncontrollable (at idle) in the water. Am I missing somthing here. Looks to me like lossen the cable and then retract the idle speed stop on the throttle body.

I did a complete engine rebuild with a supercharger rebuild (by Jerry) and the new greenwheel. I just purchased a new set of hoses. The ends on the ones I have are pretty expanded.

The hose going into the TB doesn't affect idle speed. The ECU controls the idle speed by opening and closing the idle speed control valve in the throttle body to only allow enough air to keep it at 1800 rpm idle. If you have a bad ISC valve, a leak at the TB to manifold gasket, a leak from the manifold gasket to head, a leak at the intercooler opening, or a cracked manifold, then you will admit too much air and the idle speed will be too high.
You have something really wrong for it to idle that high.
