I don't have any fault codes related to ignition, fuel, or air. I have no idea of what to start looking. Typically I would wait for an engine code and then start trouble shooting from there.
That code could be causing the symptoms you describe. Doing a throttle reset is a good idea. However, if it were me I would clear the code, both active and stored, and see if it returns. It may take some driving for the car to throw the code again as the EVAP system is only tested after a few driving cycles have taken place. If the code returns you have found your problem. The cars are 20 years old now and the EVAP system has started to come up more often on the forum.
