Both of my engines will not idle unless I throttle up. My warning buzzers will beep twice about every 3 minutes. It started with just one engine and few minutes later both of them were doing it. Any help would be appreciated. The are 6.2 mpi s

Did it start doing that right after a refuel? My motor has been through bad gas and I finally got it out. I have an idling problem that I think is plugs. Try a new fuel filter and check the plugs.

yes I did refuel. Under power it runs fines,but the alarm still beeps like it does when turn on the key. It never alarms constantly
