'86 L98 manual trans.
I replaced the worn-out throttle body w/ a BBK 52mm body. The throttle shaft and bushing hole are worn and the throttle wants to stick at 13-1400RPM.
I have the base timing set at 9BTDC and minimum airflow set at 400RPM per the book. Min TPS is set at 0.5V.
When I come to a stop, the idle settles at 1000-1100RPM for 5-7seconds then drops to 6-700RPM. Is this normal for these engines or is the IAC motor a bit slow to drop the idle speed?
