Hello, its a higher idle or no throttle response when you hit the throttle? Just idles?
Customer: replied 2 years ago.
Runs and drives great. Throttle ok. Just idles high with engine cold or warm. I've unplugged all sensors one at a time while engine running. No change. Swapped ficm and put with known good modules. No change

And no aftermarket modifications or performance chip installed?

When will someone be responding to my question. Anyone have any ideas
Expert:  Cardoctor71 replied 2 years ago.
Has the throttle plate been inspected for build up, or sticking mechanically?, this is where I would start with diagnosis.
Customer: replied 2 years ago.
No throttle plate on this engine

You may have a problem with the IPR causing too much ICP pressure. The IPR screen comes apart sometimes on those and possibly it is not allowing it close all the way to change icp pressure.
