Hesitation, stalls, weird idle..
I have a 2006 GMC 2500HD, 6.0 L
Recently it had begun to hesitate during take off or driving down the road. When in park the idle will suddenly shoot to 1500-2k rpm. Then drop back to 200-500. This has caused it to stall a few times. The ac was not on.
Replaced the throttle body and sensor. Still has not resolved the issue. No check engine code. Engined was also scanned and no errors or issues.
Becoming frustrating. Any assistance or thoughts works be appreciated.
