Anyone know how long the mass airflow sensor is expected to last?
I have 130K, SES light, and lean codes 0171 and 0174. Parts chasing with an item this costly is well, costly, but can't find a leak, and am leaning toward replacing the MAF if the lifespan is around 7 years anyway.
A few things......1st, I would think @ 130k, yes it is very likely that the MAF can be done, 2nd, did you try cleaning it & 3rd, unplugging the MAF provides a good test to see if your MAF is dead. If the engine runs better with the MAF disconnected, it is likely your MAF is not functioning.
