first my truck still has rough idle after freeway travel shakes the whole truck starting to get mini surges so im thinking ICP.

The numbers test in good range idle, and 2500 rpm. but when driving and accelerating the voltage goes into the red a 5+ volts. It doesnt read pressure so i dont know if this means ICP is bad or IPR is giving to much pressure. what do you guys think. replace ICP or IPR

My guage EDGE EVO CS shows temps within the 15 degree difference EOT and ECT. it goes from 4 or 5 degree diff to 10 to 12 and averages 8 degrees diffferent. Should the temps be exactly the same or is my truck functioning normally to have those differences. I never go over the 15 degree seperation. Just want to know if Im on deaths door or its running just fine.
