I've read here that to adjust the throttle cable all you need to do is push in the adjuster when the engine isn't running and depress the gas pedal to the floor.  A few questions on this.  One, where is the adjuster located?  Two, does the adjuster reset itself or do you have to pull it back out?  Anything else I should be aware of before attempting this?  Thanks for the help.

Its located on the firewall side of the motor, mounted to the throttle cable bracket. You push the button, and it should return to its unadjusted position, but you may have to pull it out (towards the pass side of the car). Then release the button and push the gas pedal all the way down. Its easier with the engine rotated.
