ML320 idle in drive issues!
Brand New Member and Loving It!! I stumbled upon the forum recently and appears that the community is friendly to the non-experts like myself.
My ML320 was sick with many symptoms; sputtering, no power, would not idle, etc. Got so bad at the end that it would not pull out of the garage. I replaced the crankshaft sensor, Mass Airflow sensor, plug wires & plugs, fuel filter & hoses, fuel regulator (all OEM parts). Had to reset the the radio due to unhooking the battery. The results were huge, I have my baby back..........except, it dies when idling when I come to a stop in drive or put into reverse.
I was told that it needs to be put onto a scanner/computer and be reprogrammed. From the threads I am reading on the forum, it now appears that this is probably bad advice and I need to replace something else. No other posts had exactly the same symptom, but one similar recommended replacing the Air Idle Intake Valve (AIV). Another recommended adjusting the idle adjustment. Any more detailed suggestions? Like where is this AIV or idle adjustment screw?
Broke in ALABAMA!
