So I got the $93 Buyautoparts MAFand the Durametric numbers are great. The FRA and RKAT numbers and voltage are all right on the money,where with the old MAF the numbers were pretty far off. But the mass air flow still is off.The spec is 15 kg/h +/- 1.25, the old MAF read around 13 and the new reads about 19. I also got two error codes, MAF reading above upper limit and air intake temp reading above upper limit right after I installed the MAF but they haven't come back since driving around a bit.

Now it has a slight drivability problem. The idle is hunting, almost stalling when I first start the car but it gets better as it warms up. And the power felt down a little but it did seem to improve after a couple of full throttle runs.

So is this just the DME adapting to the new MAF or something else?
