I see that others have experienced the same problem. Basically a loud constant humming noise that will SOMETIMES stop when a/c is turned on or off and also when tapping the gas pedal. The noise comes and goes; and seems to happen during the hotter months. Does anyone out there have any idea what the problem is? As I am a worry wart with no extra cash at this time, I need to know if I am damaging the truck by continuing to drive despite the noise. Thanks for any input offered!!

A loud whistling noise coming from the engine. I have no idea what is causing it. It seems to be in the air intake system or throttle body area but I am not sure.

It almost sounds like a train whistle. I can be driving, parked and idling and starts.

I've replaced my alternator, ac, and power steering, nothing has stopped the loud train horn sound, it sounds like its coming from the throttle body, i have no idea whats wrong with it, it makes the noise after it has been running for a while and is at full peak in traffic or idling, when i'm on the road it ceases to make the noise, but when i slow down at a stop it starts up again....
