erratic idle, p0507 code
Vehicle will idle erratically while driving in town. Will surge RPM's when in traffic and slowing down. It popped a code P0507 for idle rpm higher then expected. It will idle perfectly when just sitting still. Watch the video link I have attached.
Things I have tried:
Cleaned Throttle Body (No changes)
Tried a different Throttle Body (No changes and put the original back on)
Replaced EGR valve gasket (thought a leak, no changes)
Carb cleaner trick on all vacuum lines looking for leaks (found nothing)
Idle Relearn procedures after every attempt
Things the dealership has tried for the past 3 days with no luck:
PCV valve replacement
ECM flash
Cleaned idle air control built into Electronic TB
Looking at a possible ECM replacement. If they come up with a solution I will update. Searching for answers from anyone, please help before I leave this thing in a shady neighborhood with the keys in it.
