Customer Question

2004 chevy HD 3/4 ton crew cab.
Mostly in the morning when it's cold or humid or just cold. I can drive sometimes a few miles then the display reads reduced engine power the engine is running smooth but at a high idle 1300 rpm. I have no throttle control at that point. To get it to run again I turn off the truck turn it on and check the display to see if it normal and turn it on and off till it runs normal. Sometime it will reduce power 1 to 7 time in an hour.
