, there are a few articles, some on here, some on other forums, going into good detail on how to clean your MAF and throttle body. I dont have any links to them, but a quick search will do the trick. Make sure to take them both out of the truck when you clean them, and be sure to use the right chemicals when you do it. Electrical contact cleaner for the MAF and they have throttle body cleaners at most car parts stores... at least to the best of my knowledge.
