Two beep alarm and bouncy tach

I have a 2005 496 h.o that is throwing a two beep alarm every minute and the tach bounces. Engine runs fine when alarm goes off........ Any ideas

Idle Air Control.. would'nt the motor rev up and down with the tach?

IAC is a strong probability, but I would not buy or replace anything without running it on a scan tool first.

If you have a 496, or any of the motors with SmartCraft, the Rinda scanner is some of the best money you will spend on your boat.
