OK.. theres a screw on the bottom of the throttle body, paralell with the firewall. I would say its as small as 6mm or 7mm. I messed with it to adjust my idle, and now its hard for me to push the gas in. The gas pedal sticks at first then goes in. And my idle goes from 750 to 1500 really quickly. Anyone know what the bolt is called and how i can fix this?
