My 99 F-350 PS is throwing Code 1280. It runs fine for about 3 minutes then runs rough with surging rpms, then dies. Information says that this is a ICP problem...........advice? Also, if I were to replace this part, where's a good place to buy?
usually if icp sensor is bad it sets CEL and runs at a default value. Truck should still run just under powered. I would check oil level at HPOP first. If you have a scanner watch the value of ICP and see whats happening there.
