92MYSVX Auxiliary Air Valve Disconnection

If you receive a customer complaint of engine will not idle and stalls-out, check the hose from the throttle body to the auxiliary air valve for disconnection at the air valve nipple. If this vacuum hose comes off other symptoms, such as black smoke from exhaust when engine is started and the check engine light is on and no codes are found in the ECU memory may occur. Install a hose clamp at the air valve connection to prevent the hose from becoming disconnected. All 93my SVX models will be equipped with a hose clamp at the air valve hose connection to ensure a secure connection.
