I keep hearing about people taking their trucks to the dealers to get reflashed. What does that mean. My truck has been surging at low idle for no reason (By the way I live in Miami so I dont think cold weather has anything to do with it). Do I need one and if so how do I go about getting it. Thanks.

A reflash is loading a new program in the pcm. It affects the way the fuel is managed. Surging at low idle is the magic words for the dealer to reflash you truck. One of the problems fixed was the surging idle.
