Any Codes? Engine Light? A Scan Guage or like tool to collect any codes is also something that is a must in your "tool box".

This was posted under "Various Running Issues" In the tech Folder.
For those of you experiencing intermittent surging at idle and while driving at steady speed, excessive smoke, rough running, stumbles,lack of power, stalls, cutting out, erratic idle, bucking, noisy engine operation, oscillating engine noise level, and erratic EGR valve operation, the problem may be the exhaust backpressure sensor. The EBP sensors are failing internally and causing an erratic signal to the computer, or a reading that is too high or low for local altitude.
This is also the part causing the check engine light to come on with a low boost code P2263 (03 and early 04) or P0299 (late 04). Usually these codes are set at idle or at low vehicle speeds/low RPM when boost would not be present anyway. In some cases the EBP is causing EGR flow codes.
Chances are the sensor won't be acting up when you bring the truck into the dealership. The technician should check to see if the EBP base reading is the same as the MAP and BARO sensors when the key is on and the engine is off. I have found that tapping on the sensor bracket can cause the reading to change if the sensor is faulty. Sometimes starting the engine and turning it back off results in the sensor reading a different base pressure than before.
On a test drive I had an EBP drop the reading 3 PSI below what base was, when normally it's 2-3 PSI higher at idle--it's like the EBP though the truck suddenly went over 5000 feet above sea level. I have had severa trucks that would only cycle the EGR on and off while at a steady speed. If it is doing it mildly you can hear the engine cycle between cackly and quiet. If it is severe you can actually hear the turbo coming on and off and feel it surge. Keep in mind there have also be cases of the EGR valve itself sticking and causing
it to cycle open and closed as the computer tiires to get the EGR position sensor where it wants it.
If the EBP is more than 0.5 PSI above or below local atmospheric pressure, or if the signal changes when the bracket is tapped, or if the base reading changes as the engine is turned on and off or as the engine temperature changes, or if the technician can verify the above symptoms, the EBP should be replaced.
At this time there is no bulletin or even an offical notice out on this problem. A revised sensor is being tested, but is not available. In the meantime the only thing that can be done is replace the EBP with the current level part as a temporary fix until a revised part is released.
