GM  25334692 10340478 AMM - Unit removed from a recent crash damaged 3800 Pontiac Grand Prix GTP, 2004.

Up for sale is a Good working Mass air flow sensor - 25334692 10340478 car still ran, but was damaged beyond repair, it was however a "total loss" - this should be a good used unit!  I will give a 30 day warranty with this unit.  A bad AMM can cause a lean running condition, loopy idle, no start, runs but has no power, random stalling, or any other strange running conditions.   This is listed at about 1/8 what they cost from  GM
