Hey gang, I have a 99 Mazda 626, 4 cyl, and have an annoying issue I am dealing with. When the car is in drive, L2, L3, or reverse, but not moving, the idle is rough. Not to the point of choking out, but rough nonetheless. When I put the car in neutral and park, it's smooth as a baby's bottom, and so quiet you don't even know the car is running. Someone told me it might be the mass air flow sensor, but it's when the car is not in motion - does that sound right?
(I've already done a tune up, changed plugs and wires as well)
Thanks!

Car will stall sometimes when you are slowing down to stop (automatic down shifts and then rpms drop car shuts down). I have replace IACV, mechanic saying transmission needs replacing @ 3,100.
