timing functional test. Technician A states that if no manufacturer engine
speed tolerance is given, the idle speed should be within 100 RPM of
manufacturers specified idle speed. Technician B states that if the procedures
for timing check are nit found in the under hood label the inspector must refer
to the emission control application guide or the manufacturer service Manual.
Who's correct? Right Ans - Both technicians
