aTOMic,

Just curious, how was your W210 idle erratic? Was your 96 E320 idles high in park or neutral? The reason I am asking is that my 97 E320 (W210) idles high....about 1500 rpm when in park or neutral. The car drives excellent except for the high idle. Also, Do you know if the Mass Air Sensor failure a common problem on W210?

Thanks
