I disconnected my battery for a few days while I was changing out bad spark plug wires and an 02 sensor. When the tasks were completed and I drove the car, I would get a beeping sound like when a door is open or something. This only happens when I am idling, not driving. There are no SES lights and my "data center" reads "all systems OK". There also seems to be no discernible pattern or pace to these beeps, and the car idles smooth and runs (and sounds) great. All gauges (battery, temp, oil pressure) read normal. Is this just the computer running through some diagnostics or something? Thanks

Nevermind - hasn't done it since that first startup. Car runs great so I can only assume it was a series of diagnostic checks since it is the same tone as when I start the car any other time.
