Thanks for all the input, guys. I'm ruling out the cp because the tach rises as I'm cranking. Oil pressure fluctuates at idle, by approximately 100 psi, which could just be worn injectors??? It's done that as long as I've had a gauge on the truck though. Ive kinda convinced myself that its a wiring issue, either with the icp, or ipr pigtails. Both sensors are less than 1000 Mi old, both are Ford parts, and both went together just like they should.
Another reason for my thinking is because mechanical issues usually just get worse, and that isn't the case here.
I'll order new pigtails, and solder them on, see what that gets me!
