Cm870 bad fuel actuators?

[berrytrucking94]

Been getting check engine light on dash sporadically throughout the day as of yesterday. Light will flicker on for about 1-2 seconds then shut off for a random amount of time. does it cruising at highway speed, hasn’t done it when idling.

fuel actuators were damp w/ fuel around the plug and wires with some gummed up residue around the actuator itself.

Recently noticed a random skip when idling at operating temp which makes me think they could be going bad? Clogged up inside? Haven’t popped them off to clean, I haven’t done that before so any proper cleaning tips would be helpful. Truck has 427k with original actuators..
