Just did the same thing to a truck before this one same code figured it was airrrated oil. Even let truck run in parking lot for 3 hrs at 1200 rpm still same result. ![]() ![]() Replaced the IPR with a new one same result. When full throttle or pulling hill icp jumps from desired to 4917 instantly then code comes on then check engine and engine goes to open loop for a little bit then goes back to closed loop and normal power.As soon as you floor it under load it happens again. Replaced all 6 adapters and 6 injectors and ICP sensor. Pressure checked icp system leaks at adapters and 4 injectors.
