I was told there is a sight on the internet I can go to and find out what what different alert sounds (beeps) mean. I found out, as I already new, that a constant sound means problem needs taken care of immediately. I also found that 3 beeps about every minute or so, meant that there is a problem and will need attention. That was my Idle Air Valve. Any one know where I can find this information? I just heard 4 beeps yesterday, but it quit.
