I put lots of miles on the car, approx. 50 k a year. First I took it to the deal. It took them over 4 hours doing smooking test, but can't find any problems. I took it to MIDAS. They have scaned several times before and after I replaced the Canister close valve. Nobody can figure out where is leaking. Can anybody help?
Try posting this in the auto repair forum you may have better luck
SOURCE: check engine light on after
You have a leak in the fuel system somewhere or a bad evaporative system sensor, the way the system works is the control module for the emission system pulls a vacuum on the gas tank and lines to check for leaks, if it can't get a certain vacuum level for a specified time it decides there is a leak and the check engine light comes on. This may be covered under the Federal Emissions warranty, call the dealer and inquire if the Evap System is covered.

remove a negative batery connection for 1hrs and reconnect it.And down of seat you will see a connector dissconect and connect again in power off.

Sounds like it might be either the fuel filter or the fuel pump, cause if you ran the tank down, you probably had sludge in the bottom of the tank that you sucked into the engine, you can try using a fuel system cleaner, you may have sucked sludge into the injectors running it, Zmax sells a fuel system cleaner, or there is one called RUN RIGHT, I would try putting some of that in letting it sit a few min then after it sat a few to soak in and break down the sludge, then start the car up, kick your idle up to around 1500 RPM do not go higher then that cause you will damage the engine, try that and see if that works for you, if not then I is probably the fuel pump or filter.
hope this helps.

It sounds like you have either a lean or rich condition ocurring,could be exuast leak,vac leak,leaking fuel preasure regulator,cat convertor.At this point would go to dealer for diagnosis.
SOURCE: CIL on, code P0441, using more gas, hard to fill up
In the first place, P0441 = Evap. Emission System Incorrect Purge Flow. The 'CANISTER CLOSE VALVE' you mention is normally OPEN until the ECU (Engine Control Module) decides to check the fuel system for any leakage - IT closes the valve and then applies a vacuum to the system and monitors it for leakage. This valve (CCV), if sticking CLOSED, only MIGHT set P0441. The most suspect component is the Purge Control Solenoid Valve (located on/near the engine) and is also controlled by the ECU. If this valve is malfunctioning, it can absolutely cause this P0441 to SET!... There is also another component which can CAUSE this code to SET... it's the Differential Pressure Sensor (DPS) or Fuel Tank Pressure Sensor (FTPS) connected to the Evaporative Emissions System. It is this component which monitors 'vacuum' pressure on the system to determine if there is any leakage.. its signal is also used by the ECU to monitor 'purge' of the charcoal canister under normal driving conditions. There is yet another component which can cause the ECU to set P0441.. and that is a restriction in the 'purge' circuit.. clogged charcoal canister, air filter, or a kink in the Evap hose(s).
