Racing Idle on my 5.9
Been having trouble with irregular idle on my 5.9. Races to 2000 RPMs then drops down and stalls out. Oxygen sensor has been changed, throttle body cleaned, and recently the PCM (Power control module) was changed. Still racing and stalling. Dealer has no answers. I LOVE MY JEEP. This is my 4th one. My sick car needs help. If anyone has any input, I would greatly appreciate it.
