My truck is getting dead pedal at times and the mph needle jumps all over the place again now my iat sensor constantly reads 32° F and kicks itself into 3 cylinder high idle on it's own 

I would start by getting the trouble codes read with a scanner. If you dont have most auto parts stores will do it for you. Then post up what you found.

Ivd got p0602 p0380 p0113 p1693

Un plugged speed sensor mph needle still jumps when hitting bumps or randomly

As for the high idle switch jump over to the support ticket. Which I'm going to bet the P0113 is from.
