I think it's time to deal with the dreaded dirty air screws on the TB's. I've been on the GS for a while and decided to get out the RT but now it's just barely idling. It's always been too low since I've owned it. On the right side of the RT I can see what looks like an access hole in the plastic and a fairly large slotted screw down there. But I don't see one on the left side. I would really like to try and back the screws out an eigth of a turn and see if that helps, but I don't want to take all the plastic off if I don't need to.
