My Mazda Tribute '03, stalls when the heat is on and the car is idle. This only happens when the heat is on. What could this be?
Also, my check engine light came on and my mechanic got a p0509-idle air reading (if I remember correctly). Could these two issues be related?
Help!

Yes, the P0509 is idle control related and would affect the idling speed ans stalling when AC compressor kicks in.
