  1. Correct me if I am wrong. Isn't the "imt" sensor is on the cegr engine. Either way aren't they located in the same place on the intake manifold under intake ducting?
  2. We have 4 of them in our fleet. Notorious for oil leaks from lower exhaust manifold bolts and where the oil filter manifold mounts to the block. As mentioned earlier update the software. If you have an iegr engine and have to fix leaky exhaust manifold bolts, replace the exhaust manifold with older version (less restriction). Also had wiring harness issues. All in all the are decent trucks.
  3. Do you have fuel at the injectors? Crack an injector line open, crank the engine, and see if you have fuel that far.
  4. In a pinch I have just put a peice of hose on with clamps to get the truck home. Then I fix it correctly at the shop. Ultimately there should only coolant pressure there (no more than 15 lbs.) unless there is an issue with your engine.
  5. I have a 05 e-7 iegr engine with a 2-3 blink code. FMI 5. I need some help. I have replaced the IAT sensor. The wiring harness is new about 10 months ago. I followed the diagnostic tree for the code and it went away for a couple of days. Now it intermittently comes back on and goes back off. When the lightning bolt comes on the engine fan stays engaged. The plugs look good at the sensor and the ecm. So do the pins. What am I missing?

    Has anyone attempted to repair a leaking harness at the back of the engine? Any success? Outside of a compete harness replacement?
