truck dies in high idle when hitting brakes

Hey guys, i might not have a problem just never seen this.. I changed out my glow plugs, harnesses, along with alot of other items- truck batteries died after sitting in the cold for 2 weeks... Recharged batts and all is fine. While starting, truck fired up, after 1 minute, high idle came into play, let the high idle run for a couple mins and i hit the brakes... Truck died and would not restart- read code and it read an IAT sensor to high or something? cleared code, truck fired up and ran like a champ.. Is this in the program on the high idle mod? I normally touch the gas pedal to get the high idle mod to stop. thanks!

Touching the fuel pedal or brake will deactivate the warm-up idle. It obviously shouldn't die. Has it done this repeatedly?

Maybe it just needs to go through a few drive cycles?

Sent from my phone that somebody didn't help me get.

i wouldnt worry about it unless it happens multiple times. not to mention you just reset your computers so let the truck get its feet back on the ground.

Yes i hope thats what i was.. drove it all day and batts charged fine and ran ok... I noticed though that maf sensor on the intake tube was loose? the back torx sercurity bolt is stripped.. I took it off and clleaned the sensor with mass air flow cleaner.. Thinking about getting a large hose clamp and using that to tighten down the sensor evenly on the intake tube.. could this also be an issue? When i had it apart i cleaned the map hose and fitting, cleaned all cac pipes, new boots and cleaned intercooler.. so i know thats all good and tight
