Generallee Posted October 10, 2017 Report Share Posted October 10, 2017 Anyone know anything about the purge valve and evap system? I understand this only operates when the engine is hot - does it operate only when the motor is off tickover? If I disconnected the connector off the valve above the canister in the front arch, would it stay closed? If it were sticking open, that would cause my erratic idle that only occurs when hot???? No codes in the car. Link to comment Share on other sites More sharing options...
