Hey guys. I need some input. Internet is giving me 2 different answers. I'm going to replace my Mass Air Flow Sensor, and some places say I can just unscrew the small sensor from the top of the housing, and some places say I cant, and have to replace the whole housing. Has anyone done this, and which route did you take. It's for a 2000 XE. 3.3L. Thanx guys!
