[QUOTE="ChopTop84, post: 1540152, member: 19210"] You need my autoenginuity scanner. ford/international was not required to meet the exact OBD2 spec, so the majority of OBD2 readers dont work correctly. My AE can do the IPR duty cycle monitoring, that a reader cant do. ICP sensors do fail. They have to monitor 3000+ psi pressures. Thats hard work. Pull the icp plug out of the sensor, and use a pair of needlenose pliers to gently squeeze the female pins tighter. Also, look inside the sensor itself and make sure there is no oil or fluid inside with the pins. If so, the sensor is probably failing. ICP and IPR create a feedback loop. If one acts up, the other tries to compensate, and it can create a surge or rough idle. Ideally you would monitor the ICP and IPR readings with a live scanner while the truck is acting up and see which one acts up first. whats your schedule? [/QUOTE]
