4. Before starting engine reset Idle Air Control valve pintle position:
A. Turn ignition switch to the "ON" position.
B. Ground diagnostic "test" terminal for five seconds.
C. Remove ground.
D. Turn ignition "OFF" for ten seconds.
E. Start engine and check for proper idle operation.
NOTE: Disconnecting PCM from it's power source will clear all PCM memories. Since some operations (particularly IAC valve idle control) are
"learned," it may be necessary to partially depress the accelerator pedal when restarting the engine after PCM memory is cleared. It may also be
necessary to release the accelerator pedal very slowly when returning to idle, to prevent a stall. This will allow the PCM to "relearn" IAC valve
position.
5. Learned operations may be restored by normal driving.
