idle at 800 rpm and surges

[Rawze]

Start by assuming the program is a bad delete.. I don't care how many years it seemed to run ok. For all you know, it might have finally or suddenly shifted engine operating modes and is now stuck in a DPF warmup perpetually.. making it run bad. Without first establishing this, it is anyone's guess.


Copy the program out of the ecm and e-mail it to me for a proper review of what someone did. Good, bad, or downright ugly, so that you can eliminate this as a strong factor.... and simply for piece of mind to know you are not using harmful programming that eventually will take its toll on the engine.

also, someone needs to run the overhead valve adjustment on it and do an injector leak test.
