My truck has a 5.0 with a 5 speed transmission. When turn on the defrost or the A/C the truck stalls. I thought it was the Idle air control valve so I replaced it. Still stalling. Next I thought maybe the throttle position sensorwas bad. I replaced it, still stalling. I have a code scanner and have retrived codes from the computer and there are no trouble codes. At this point I am at a loss as to what the problem is and am contemplating taking it to Ford to see what they feel is wrong. Would you happen to know what the problem might be?
have the same problem?
