Now my linkage is absolutely perfectly set on the throttle body..if i turn
it in and all, my throttle body begins to open........so, I guess that
leaves the other end> It appears to have slack at the transmission end, but
up above the spare wheel, the cable is already thru the clamp about 1
"..........WTF? When I step on the pedal it feels good, not like there is a
dead spot........
I know we can get this right! I would love to have an 800 to 1300 rpm
difference in shift points. That would be about right.
