1989 Pontiac Trans Am GTA Fuel Injection Tuning - 101 Tech Idle Mischief
|
Minimum-Idle Adjustment: Low-Idle Speed - With the car completely warmed up and in closed-loop mode, we turned the ignition off and used a paperclip to make a "U" shape to short the A and B terminals on the ALDL (the socket is located under the dash by the drivers' right knee). The far right terminal is A, the ground, and the B is the diagnostic. We then turned the ignition on but didn't start the engine. After waiting 30 seconds, we disconnected the IAC valve connector.
