My guess is you have the 2.2 motor. If I am right,

PO440 has to do with a problem in the evaporative system, possible sealing, purge valve or solenoid problem. Pretty tough for a do-it -yourselfer. Either you throw parts at it or have a shop with quality scanners and smoke machines diagnosis it.

Cancel the appt. If the light isn't on, don't worry about it. It very well may have been the cap.

I wouln't take this to your mechanic. It would be an insult, I'm sure he is well aware of the system.

With the money you saved, maybe you will send a donation ?
