I am trying to remove and clean my MAF sensor from my 98 CSVT. I read the how-to but i am still unclear as to where exactly the MAF is located? Is the MAF the little black sensor on top of the metal intake duct right after the air filter? there are two bolts, one is a star head bolt, and the other is more like a rivet. I cannot remove the other bolt. My question is, do i remove the metal duct the sensor sits on (attached by 4 bolts)? If anyone knows, i would appriciate it.
