That adjustment screw for the TB is the one that I messed with last time and it took me about 6 months and 300$ in parts to figure out that's what was causing my horrible idle and general crappy running condition. (By the way, NONE of the parts helped it run better then, but I'm sure they can't hurt performance now that the new TB is on there) That's the one that adjusts the amount the TB butterfly is open, correct?
