2007 opti 225 don't have the serial number handy Im getting a solid beep beep beep for a few seconds while running at 5000 slow to idle still beeps shut it down restart and no beeps Its not the typical low oil 4 beeps or the steady beeeeeeep over heat warning alarm. The DDT shows no faults I can go days with no alarm then out of the blue it does it , Shut it down wait a few seconds then it will be fine for the rest of the day or days. Battery reading is 13.4 while running no overheating issues This one has me stumped. Looked this alarm code up and there is no beep pattern listed that Im getting BTW motor runs great no loss of power doesnt go into guardian mode just the annoying beep Any ideas
