Hi,I have a 2005 F250 and I seen posts about cold starts and running rough,my question is: What is everyone talking about when they say,DEALER REFLASH? I'm new to owning a diesel.The truck is bone stock.
Reprogramming the trucks computers to alter the running parameters. If you haven't had it done since the truck was new Ford has a very good program that's beneficial to the health of the injectors and improves cold starts.
