A couple weeks ago my 01 7.3 with 265,xxx started ideling rough and stalling. I had driven in all day Sunday and the next day it started out of the blue! It would barely start idle rough and stall out no CEL. I have singed changed the icp, fuel filter and I have checked oil level. Also used fuel cleaner. Still had no help. When I changed the icp sensor the check engine light came on and was no change I then got a ford oem camshaft sensor and my truck fired right up but still sounded like it had a little miss here and there drove it for a few weeks fine now back to the same thing it will start up and idle fine for 10 seconds then start the rough idle but won't stall out anymore just idle rough. I am stumped I can't get any codes to pull up and if oriellys uses there scan tool while the truck was running it would shut the truck off! I can't find any answers and I need help please

 

Check the UVCH, 42 Pin Connector, Chafing of the Wire Harness Drivers Side Valve Cover and IDM Connector for deficiencies and contact issues.

 

X2..........

 

Does this happen when the fuel tank gets low?

 

Has half tank of fuel just started happening out of the blue

 

Check tin nut on IPR

 

The ipr feels tight but the connector that the plug goes in moves side to side is that normal

 

Yes. If you were to loosen the tin nut the electromagnetic can slide completely off (it's meant to do that). You could try taking the IPR completely off and cleaning it and putting new orings.

 

Check your UCVH connections yet?
