Throttlebody Adjustments

[65gtmustang]

Is there a feeler guage setting for the throttle butterfly (how far it is open)before you set the tps up.Any help much appreciated

Under normal operations / setups, the butterfly is fully closed to the bore. The closed stop is adjusted to prevent the butterfly from closing enough to possibly get stuck....

Thanks for that,managed to confirm with toyota agent that is how they are set

yeah, the ISCV handle all idle air supply..... If the butterfly is open even a small amount, the ECU will tend to have a hard time controling idle consistantly...
