Update, I removed and cleaned the EBP sensor, tube down to the exhaust manifold. Not very dirty. I also removed and cleaned the MAP sensor port on intake manifold. Removed all duct work and checked for holes/cracks, found none. Put everything back together, fired right up. Could hear turbo spool up nicely, early boost noted on gauge when first pulling out. Got about a mile down the road and started acting back up. Died three times, a booger to crank back, limped it off the road and there she sit's! Idles right where it is supposed to, then idles started having a few misses. Turned off and well...still there!! I'm about ready to put a 50BMG round between the head lights and call it a day.
Still not had it scanned yet.

OK, finally got it scanned. Everything checked out except for the ICP sensor. It threw same codes 3 times, and every time we had just cleared them! Checked the sensor and it had some green discoloration at the electrical connection. So I guess water had gotten in there when I had worked on replacing the injector and FICM. I don't know if it's bad or not a bad connection. Can I clean it some how, or just replace the sensor and pigtail?
Oil pressure would run idle at 840's+ and revved would go to over 1000+.

Why should you buy it from Ford?
-2 yr unlimited mileage warranty
-It's the correct sensor
Parts store sensors are never an exact replica of the Ford sensor and are usually missing a component or something was modified so Ford couldn't/wouldn't sue them.
Ask me how I know...

Unplug the ICP for about three days and see if the problems go away. If they do, it is a bad ICP sensor or pigtail. If they don't, it could be a bad ICP pigtail or the HPO system (IPR, leak, etc).
STC been replaced yet? Are hot starts more difficult than cold starts? If so, it points to a HPO system problem.

As soon as I cleared the area, the truck ran normally. This is because the O'Reilly ICP sensor isn't shielded and RF and other frequencies can interfere with the sensors signal. The Ford sensor is shielded and doesn't have this problem.

Ok, update replaced the ICP sensor and runs great.
Now on to next project. Replacing the boots on the Hot side of the turbo and inter-cooler.
Who and where to buy from or stay away from?
