Limp mode issues
I have a 01 Duramax, It will throw a PO093 trouble code and go to limp mode. I have had a new fuel pressure regulator put on it and the injectors have been done under warranty before I got the truck.
It will throw the code very randomly, loaded or unloaded. Does anyone have any ideas on what could be causing this? My guess is maybe the throttle position sensor?
The truck runs way to good to be something major, I think. Also the truck has a 4 inch exhaust and a K&N filter, but has never had a programmer of any kind.
Any help you guys can provide would be great,
