1995 3.0L 225 efi - beeping during warm up

[Seanj85]

Motor is beeping when I turn my key to the on position while cold. When I crank it up it will continue beeping and seem to run rough for a minute or so. Once it runs for a minute or two the motor seems to smooth out and the beeping stops.

The beeping is a continuous intermittent beep - beep - beep. NOT the solid beep or 4 beeps every 2 mins.

Any help is appreciated.

Just about have to hook it up to dts. Everything from sensor fail to cold idle.

I think it has gremlins. I have twins, can I switch any sensors out between them and do some diagnostic work?

[Motv18]

If you’re willing then probably. Not sure where to start though. Because it could be injectors

finding the ohm specs is normally easier than swapping.

Just did injectors last season along with complete rebuilds of fuel system.

Anyone else on this?
