Go to either the dealership or autozone. They can use an obd2 scanner to pull the code from the connector under the steering column.

If you know anyone that works at Jiffy Lude- they have the scanner as well.

Sorry for the delay guys...I had to get the car checked out.
The codes that the garage gave me were P0-462 and P0-457.
The 462 one is Feul level sens circuit low volt .
457 is Evaporative emission control system leak detected...
Can anyone explain this to me in english please?!?!?

thanx.

Well...by chance do you have a manual boost controller? If not, what setup do you have?

ok...maybe I made a mistake on the original diagnosis.

One more question. How many times have you filled up your gas tank, while your car was running?

Almost all the time actually... The last few days have been pretty cold so I leave it running...think that has something to do with it?!?!?

Yes it does. The WRX has a sensor to make sure the fuel tank is pressurized (i.e. doesn't leak or have holes). Since you fill up with the car running the sensor stays on and detects that as a leak in the system. Turn the car off before refueling and CEL will go away after a while and this won't happen anymore.
