Adjustment screw on the TB. It adjusts the throttle butterfly. I had no idea it had one but it does. I pulled the TB off again and took a 2.5 MM allen wrench and turned it one revolution and put the TB back on and voila. Can you say DOH!!!!!!
Apparently over the years and mileage it had wore a little groove in the throttle lever and it allowed the butterfly to close too much. Who knew??
Now that's something I never would have guessed on a late model. Glad it's finally fixed!!!
