4th of July weekend I was about 500 miles from home when I was fueling up and noticed an oil leak. I decided to head home and watch my oil level, truck ran great and got me home, left one heck of a mess on my undercarriage and on my white horse trailer. A week later when the temperature dropped to 95 degrees at 9pm i went out with my steth a camera (Cordless Digital Inspection Camera) and found the leak coming from the ICP sensor.

Long story short I was to lazy to fix it myself so I bought the part and had a mobile mechanic come out the we use periodical. He dug into the project started by removing my air cleaner housing, then my fill tank, at what time he broke the hose assembly the this connects too, then the computer off the valve cover. After all this he then decided he should remove the turbo at which time I said stop!! I told him how to do the job by removing the rear shield and replacing it from there. He then ran to ford got a new hose assembly put it back together started the truck check everything and headed down the road.

This is where my problem starts next day I got in the truck and started it and thought it seamed to be running rough. It didn't feel like it had the same power that it had prior to some dip sh@t working on it at about 40 miles an hour it shook like it had a tire out of balance then it went away at about 45. It ran great at higher speeds after about 8 miles it heated up to red line on the Gage so I pulled over and got out to check it and it didn't seem hot. Got back in and it read normal again got going again and it heated up (I thought like the old gassers the thermostat was stuck) went home replaced the thermostat, temp sending unit and found the exhaust pressure sensor broken to so I replace it and flushed the system.

Started it up and headed down the road and she ran great. I got on the freeway and she was purring then all of a sudden the temp started climbing again and red lined. I got off the freeway and cruised home and the temp gage kept going from normal to warmer to red-line and back. This is were I am asking for your help does anyone have a clue what could be doing this

By the way sorry for rambling on I am just a little fustrated and mad that I let some spend 5 hours screwing with my truck when I could have done it 1.5 hours.

 

OK the rough running thing I found out this morning after tearing everything he did back down was the injector connector was unplugged on the rear drivers side, this was not because he unplugged it but he broke it. I put it all together hoping that was the problem and it fixed the rough running but not the heating up part.

Couple thoughts he did not clean or change the ICP plug, is there anything that could be caused from this, do I need to have the truck re flashed?

I have a new fan clutch coming I thought I would try that, as I said before the truck is not heating up it just the gage and the check gage showing that it is.

Any ideas would be great, Thanks

 

I am having the same trouble. When Turned the key on first thing this morning it say check engine temperature and the gauge was pegged hot and my bully dog outlook monitor read 300° before even starting it. Once started it ran real weak and steady showed these reading. then all of a sudden everything dropped back to normal. Did it again when I started it for lunch. I have a buddy at the ford shop locally and am awaiting his call back for his opinion I will post as soon as I get it. Hopefully its just a faulty temp sensor.
