You put the 6637 on and lost high idle? Did you also loose your cruise? I magically lost both one day, then I found a connector hanging one day under my engine bay, confused on where it went i looked and it needed to go on the master cylinder towards the front. They both came back! It sounds like you knocked off the connection excepically if you were putting on the 6637, i think its called a BPA switch? I did not even know what the hell the connector was then someone posted about no high idle or cruise and then i dawned on me that what i had wrong and i fixed it.

That is the BPA (Brake Pressure Applied) switch.
Although I would think and unplugged IAT would be more likely. With it unplugged the default temp the pcm uses is above the trigger value for high idle.
What did you do with the sensor in the bottom of the rear of the airbox

well the other day I unhooked the batteries for a couple hours and pinched the sensor between the filter and master cylinder and when i hooked everything back up, the truck fired right up and the high idle worked again. Thanks guys.
