Your truck is going into "limp home mode". Their is a problem with the fuel injection system. quite a few possible causes. possibly 1. pressure regulator failing. 2. fuel pump failing to provide proper pressure. 3. fuel filter 4. fuel line partial blockage between the tank and the fuel injection pump. There may be other causes and the items I mentioned can be difficult to check out. Good Luck!

On my 2000 chevy silverado 2500 with the 6.0 when i start it it starts up just fine but stumbles down to about 200rpms then picks up and drops back down to 200rpms again it does this 2 or 3 times before it...


Try cleaning throttle body and IAC sensor.Thats more than likely the issue.It carbons up over time and sticks..Another problem could be in your air intake sucking to much air.Try those and you will most likely fix your problem..
