Any OBD fault code? 01247?

Any hose split or loose?

no the idle speed nice .But a few times revs to 2500 and down a strange sound from carchoal canister.And also in the idle the car turn off.A hoose from charcoal was loose and fixed.If charcoal has problem what the behavior of the car?

See Simos 2P schematics. The charcoal canister 14 has 2 hoses: one hose coming from fuel tank allowing fuel vapors from tank to be stored in the canister, and another hose going to a solenoid venting valve 12 controlled by ECU 13. Another hose goes from venting valve to TB. This is called the EVAP system. Fuel vapors are not vented to atmosphere, but sucked into TB and burned usually when cruising.

Problems caused by a fault in the EVAP system:

Poor fuel economy A leak in a vacuum-valve diaphragm can result in engine vacuum drawing in a constant flow of gasoline

vapors from the fuel tank. This usually results in a drop in fuel economy of 2 to 4 mpg.

Poor performance A vacuum leak in the manifold or ported vacuum section of vacuum hose in the system can cause the engine to run rough. Age, heat, and time all contribute to the deterioration of rubber hoses.

There are specific tests you can do using a VAG scanner. They will tell you if you have a stuck open venting valve or a vacuum leak.
