During the course of driving, the throttle cable may gain some slack and will be in need of adjustment. This is particularly important for those vehicles equipped with automatic transmission since this may affect the shift points of the transmission.

Tools Needed:

An allen wrench set to remove the hex bolts on the throttle cable cover
14 millimeter open end wrench

Procedure:

1. This adjustment is made easier if the engine is cold and the car has not been driven. If the engine is hot, be careful around the intake manifold and throttle bodies since they'll be hot to the touch. To access the throttle linkage cable, remove the four hex bolts that are holding the throttle cable cover to the manifold (4 x 5 mm hex head).

2. The cable on the driver side is the throttle cable linkage. The one next to it, on the passenger side, is for the cruise control. To make the adjustment, loosen the front nut (1 x 14 mm) while holding the back nut, turn counterclockwise, looking from the front. Next, loosen the rear nut (1 x 14 mm) clockwise, looking from the front. To tighten the cable linkage, pull on it, going towards the balance tube. To loosen it, pull it towards the front of the car. It will probably need to be tightened; once there is little slack in the linkage, tighten both bolts, re-install the throttle cable cover and the bolts.

This will also improve throttle pedal response feel.
