Throttle Issues

[bell4x4]

I am new to the Diesel world i have a 99 2500 4x4. The problem that i am having is when i start it up and barely press on the throtle or press the throttle to the floor it will only go to 1500 RPM. I can take off the negative battery cables for about 30 min and reset everthing and it may a run couple of months and then it will happen again. Can any one give me some insight on what to do to fix this problem?

The the battery disconnect is doing is killing the APPS calibration. How to calibrate the APPS sensor. http://articles.mopar1973man.com/2nd-generation-24v-dodge-cummins/26-engine-systems/258-how-to-reset-calibrate-apps-sensor Showing that disconnecting the batteries doesn't erase anything.

As for why it changes is most likely a battery cable issue or internal ECM issue. So my question is any error codes present when this problem occurs.

I also forgot to say that after diconnecting the battery cables i recalbrate the APPS sensor. I noticed in the video that there was a device to read the codes is that the only way to read the codes?

Any OBD II code scanner will work.

I had no codes pop up on my truck.

I replaced the battery cable ends and it solved my problem

Must've been a bad ground?
