Engine sputter in idle/hesitation upon acceleration

Question type: Maintenance & Repair

I recently purchased a 1994 ford econoline E150. It sat for
12 years until a year ago according to the seller. It only has
112,000 miles. I've got new spark plugs to install,  used
seafoam with 16 gallons of gas(i noticed a slight less
studder afterwards)today it studdered/cutting in and out so
bad at idle it died, but started right back up. I'm not sure
how to explain it, rough idle, hesitation, ect..in idle and
acceleration. Any advice on where I should start or what it
could be? Fuel relay,pump,filter,injectors?plugs,plug wires?
MAP, 02 sensors? Air manifold, intake? Throttle body?
Please.....

Clean out the entire fuel system starting with the gas tank.

Another symptom that makes me lean away from fuel issues is that it doesn't hold a steady idle, and when I let off the gas and coast It almost feels as if someone is tapping the gas peddle...I do appreciate all advice.
