I have had issues with the "check engine" light for months. I replaced a few things, such as plugs, wires, etc., but now I am getting two error codes (P0172 and P0175), which the auto parts store guy says is most likely the mass air flow sensor.
Before I go out and by this $80 to $150 part, I am concerned it could also be the O2 sensors, which the codes list as secondary causes.
The vehicle is a 2005 V6 ST with Flex fuel engine and 133,000 miles.
I would appreciate advice as to how to proceed - especially from those of you who have been through this - and any tips on the least expensive ways to get the sensors.
