wher is the mass air flow sensor?

whwer is the mass air flow sensor so i can try cleani ng it and seeing if it fixes my problems?

 

It should be a few inches above the airbox on the intake tube. It should have 2 little screws holding a squarish looking thing onto the intake tube, you shouldn't be able to miss it.

 

Look where your air filter is. On the back of the air filter box is an aluminum fitting about 3" in diameter about 3" long with an electrical fitting attached. That's it. It is connected to the engine by a plastic tube about 2 1/2 feet long and 3" diameter, which is the rest of your air intake system. Air flows in the air filter, through the MAF, through the intake tube, through the aluminum intake manifold, and into the engine. The more the better.
