Doing some routine maintenance chores - including changing the air filter. Decided I would pull and clean the MAF sensor while in there. The studs that hold the sensor to the air cleaner cover are turning - I can't loosen the nuts. Looking at the other side, it appears that there is a cover held on with some small torx screws. I don't have the torx bit to remove the cover, and I am not sure that I would have access to the hot-wire resistors to clean them if I remove the cover. I am kinda stuck at the moment. Suggestions?
