It's been to the dealer twice, first time they said the air flow sensor needed an "update" which they did. No change, second time they see nothing wrong on teh computer. I have changed teh air filter (k/N), air pressure in the tire @ 40 lbs, and have changed the oil. The dealer doesn't know what to do, and neither do I. It's getting to the point where I might have to get rid of it.
Has anyone run into this, and more important, any solutions? I'll try anything, I like the truck, and don't want to get rid of it. Thanks!
