Buy a MAF Sensor from AutohausAZ and be done with it.

Should I get the whole thing or just the sensor?
Do you know how much is just the sensor?

Thanks,
Steve

I would just buy the whole thing personally. It's cheap enough.

2004 ML350

MAY I PIGGYBACK - I HAVE THE SAME PO171 AND 174

I have similar problem. I already replaced my MAF with a brand new OEM Bosch, erased the CEL but after a few trips CEL came back. My 2004 ML350 is also getting closed to 100,000 so I replaced the plugs and wires with OEM Bosch plugs and NGK Platinum. Any recommendation? My mechanic mentioned it could be a problem in the fuel injection temperature sensor? Any idea? Thank you for your advise.
