The problem I'm having with my wife's '01 4cyl LE is the "check engine light" came on. So, I got out the code reader and it shows EVAP emission system problems (p0440, 441, 442) I looked around the car, the gas cap is missing. I purchased a new cap, erased the codes, ran 1 1/2 tanks of gas through it. Now, the light is back on with the same codes. Any ideas of what this may be caused from? I hate to take it tho the "stealership", but the emissions nazi's don't care for the light in GA.

what the EVAP emission thing is talking about is the new cap is not keeping the gas fumes in the tank so it is not holding presher and thats what is giveing the the code gas cap

So do you think the the new gas cap is bad, or is there a leak somewhere else?
