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 carhas not been driven. If the engine is hot, be careful around the intakemanifold and throttle bodies since they'll be hot to the touch. To accessthe throttle linkage cable, remove the four hex bolts that are holdingthe throttle cable cover to the manifold (4 x 5 mm hex head) (yellow dotsin 1.). 

2. The cable on the driver side is the throttle cable linkage (greendot in 2.). The one next to it, on the passenger side, is for thecruise control. To make the adjustment, loosen the front nut (1 x 14 mm)(yellow dot in 2.) - counterclockwise, looking from the front. Next,loosen the rear nut (1 x 14 mm) (red dot in 2.) - clockwise, lookingfrom the front. To tighten the cable linkage, pull on it, going towardsthe balance tube. To loosen it, pull it towards the front of the car. Itwill 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.
