RE: Adjusting trottle valve cable
here, try this... pulled from elsewhere...
1. Turn engine off,
2. Remove air cleaner
3. verify that lever on throttle body is at curb idle position. Then verify that the transmission throttle lever is also at idle (fully forward) position.
4. Slide the throttle valve cable off of the throttle body. Carefully slide cable off stud, do not pry or pull cable off
5. Compare position of cable end to attachment stud on throtle body lever.
Cable end and attachment should be aligned (or centered on one another) to within 1 mm in either direction.
If cable end and attachment stud are misaligned (off center) cable will have to be adjusted.
6. Reconnect cable end to attachment stud. Then with the aid of a helper, observe movement on transmission throttle lever and lever on throttle body.
If both levers move simultaneously from idle to half-throttle and back to idle position, adjustment is correct.
If transmission throttle lever moves ahead of, or lags behind throttle body lever, cable adjustment will be necessary. Or if throttle body lever prevents transmession lever from returning to closed position cable adjustment will be necessary.
1. Turn ignition off.
2. Remove air cleaner.
3. Disconnect cable end from attachment stud on t-body. Carefully slide cable off stud, do not pry or pull cable off
4. Verify that transmission throttle lever is in fully closed position. (curb idle)
5. Pry the T/V cable lock inot the UP position. This will unlock the cable and allow for adjustment.
6. Apply just enough tension on the T/V cable to remove any slack in the cable. Pullin too tight will cause the T/V lever on the trans to move out of its idle position, which will result in an incorrect cable adjustment.
I tried this a while back and it seemed to help pull the slack out of the cable.
