I am having an issue with this truck, when the truck is idling it runs fine, but when you release the park brake it runs erratic and rough? And if you drive it, it will intermittently run fine. The truck is a KW T800. Any recommendations on were to start?

Is it your truck? Has there been any wiring work done? Inspect the harness pretty closely, or maybe try a test ECM if you can source one.
