ANYONE HAVE ANY IDEAS?
Ok let me give you the run down....02' F-250 7.3L 260,000 miles. Oil changed every 3,000 miles. Cranks fine..no blow by out the oil fill cap! Runs for about 30 min. then just dies... pull code P603 kam error. I have 3 brand new CPS's a blue, black and grey. I have tried all three and still have the same results.
Changed fuel filter, air filter, 2 new batts. Also its stock was running superchip but pulled it out to see if it was the problem but still does the same.
If you have any ideas please send them my way!
Thanks in advance for your help!
