2003 ML320 problem
Hello and thank you for your help ahead of time!
My wife has a 03 ml320 and we've been having some trouble with it lately were it will seem to losse power for about 2-3 seconds and then regain it again.
Happen to me two times tonight on the way to the store I was going 50 mph and then I slowed to take a right as I pressed the gas to speed up again the rpms dropped and it took 2-3 seconds to regain rpm above 500.
but runs fine after ward's. Just replace the idler pully and belt pully melted down!

Was the triangle flashing?
Did you use a pro level scanner to check for codes?
