The throttle cable is connected from the throttle body to the transmission at front near the lower radiator hose. Adjusting is via the nuts as shown in the diagram.
Loosen the upper nut until there is some slack on the cable at the throttle body side. Slowly tighten the nut till the slack is just removed and then tighten the lower nut till it locks.
The throttle cable should be synchronised to operate in tandem with the throttle opening of the intake manifold.
Since you are not familar with the adjustment, mark the initial position first so that you know how much you have adjusted. You might need a few tries to get the desired position. After each adjustment, test drive the vehicle first.
Btw if the shifting is erratic, it could be caused by a bad throttle position sensor. You would have to test the sensor and the best way is to use a diagnostic machine. Manual testing would require a DVOM and a wire harness.
