If it's dirty or faulty, you'll run rich. You're car will dump more fuel to compensate. I'd clean your MAF and then see how it runs after. Sounds to me, from what you described, that may be the problem.To clean it, you'll need a T-20 torx security bit (you can pick one up at any hardware store for less than $2) and some Mass air flow sensor cleaner (this can be picked up at any auto parts store for around $5).1.Remove the MAF housing from your intake.2.Using the T-20, remove the MAF from the housing (should be 2 screws).3.With the MAF out of the housing, CAREFULLY set it somewhere safe to be sprayed with the cleaner. Let it sit for about 10 min. to dry. The cleaner dries pretty quickly. Again, BE CAREFUL. The sensor itself is extremely fragile. If you touch it or break it, you'll have more problems to worry about.</blockquote>
