I'm a new member and think this site is GREAT!!!

Anyway, I has been reading some previous posts where the Check Engine Light has come on with P0170/P0173 and its been advised that 90% of the time it's the mass air flow sensor. In my 1998 ML320 ONLY code P0173 registered. Do you believe it is the same problem or something different since P0170 did not also register.

Thanks again,

Erik
