Hi there,

A few months back I had a power loss problem, one of those "can't get past 2000rpm" issues. I determined it was the MAF and replaced it recently with a new one. The power is back now, the car runs better than any time before. However, the idle is messed up. It drops way too low, especially if I turn on the fan or something...in fact it drops so low sometimes that the car shuts off. If I take the old MAF and I put it in, the power problem is back, but the idle problem is gone. Now I read that there is no need for an ECM reflash after MAF installation, though this MAF is pumping quite a bit more air than the old one even though it is the same model.

Nissan technicians are saying that they need to do a computerized idle air volume relearn (I tried the procedure from the FSM without Consult II but to no avail) after I replaced the MAF but different technicians are contradicting that. Any clue as to what is happening or better yet, any advice?
