FYI re:machined throttle bodies
I had my TB machined out and when I installed it I noticed a VERY annoying issue. The accelerator pedal had to be "hit" harder than normal to get the blade to open up from idle position. Once the blade was off the idle position it was OK but a pain for stop start city driving.
I had to remove it and polish the blade edges so the fit was not so tight in the bore. Every so often after the car sits for a few days I still notice that the very first off idle movement sticks. I think I used 400 grit emery to do the deed.
