Okay, got the error code checked at my local Union 76 station. They guy was going to give me a freebie, so I flipped him $25.
So here's the scoop on the CE light error code: 00171 or P0171, meaning "system too lean, bank 1" according to this MBZ OBD2 fault code manual
Now if I go to a different MBZ OBD2 error code link
, it also adds "faulty mass air sensor" to the description.
Can anyone confirm this is the correct interpretation before I go out and spend $250 on a new MAS?
