I have a 2000 ML320, Bought the OBD2 reader, When the engine is cold, it dosent want to start on the 1st try, it will on a 2nd try, it runs rough until it fully warmed up. I do keep =getting a code P0100, I have replaced the Mas Air Sensor with a rebuilt, was still getting the same code, Replaced it with a new one, Took it to the dealer where they put it on there computer, renormalized the setting, Still having the same code & issue.
Any Ideas??
