My service engine light is on as of now, but i had the codes read and they said it was the Evap vent valve solenoid. I have no idea what it is or what it does, and for that matter i have no idea where the damn thing is to change it. the truck runs fine, its just seeing that light everyday that annoys me. I also have an extended warranty on my truck, but they have been very good to me. I'll have to see if they cover that kind of work(emissions). I've had a new drive shaft and yoke replaced on my truck already and the warranty coughed up the 800 bucks no problem. I still got like two years and 16k miles left to go on it.
