Actually, I have experienced what I would call a noticeable decline in performance when an MAF sensor is on it's way out. But, this occurs during a very short "window" of time just before the sensor fails and triggers a cel. Maybe you should consider returning it for a replacement and see what happens .

Thanks. That's what I'm going to do. Since the seller has a 1 year warranty and I do need a new MAF I'll definitely try a replacement from this guy. Probably was a bad unit and my bad luck!

Question though. Do you have to reset the ODB (battery disconnect etc) so that it learns the ways of the new MAF? The reason I'm asking is i tried to put the old MAF back and man was it creaking and groaning and fluttering.

The are a couple of techniques regarding the battery disconnect. If my memory serves me correctly, one way is to leave the negative terminal disconnected while installing the new sensor. Then afterwards, turn the ignition to the full on position for approximately 60 seconds, and then remove the keys from the ignition before starting . Hopefully some others will chime in.
