A dirty throttle body may cause low engine idle speed or frequent stalling, as oily residue blocks air flow in the throttle when the throttle is closed. Throttle body cleaning may be necessary to correct this condition. Our technicians caution against spraying cleaner directly onto the throttle body as this may damage the throttle position sensor (TPS).
