Engine stumbles and service engine soon light on

1999 F250 5.4L Triton 2wd with 94000 miles. Purchased truck used last year with no maintenance history. This just started happening yesterday. Engine stumbles when idling and driving but has plenty of power. Does not feel or sound like an engine missing. The “service engine soon” light is on. Has new fuel filter about two months ago as routine maintenance and just replaced it again today thinking it might have been the problem. Less than 2500 miles since last engine oil, oil filter and air filter. Fuel tank is full with good fuel. Went to AutoZone but no codes.
