03 6.0 studders and dies
So my buddy's 03 grocery getter F350 with 110k on it has been dieing on him. It starts right up in the mornings, then he drives it for a little while then it just starts studdering and shaking then dies. It won't start back up right away. It has to set for a 5-10 minutes then it will start up. Sometimes when it does it runs bad sometimes it will run fine. Next day same thing. I have checked the voltage on the FICM and it is a consistant 47.5 and when he starts it 47.9. NO engine light so we can't get auto care place to pull codes. so give me some thoughts... ICP? how to test or check it?
