I got a 97 ford f150 4.6l tht was sitting for 4 years cuz of broken shackle. I fixed the shackle, fresh gas, changed the oil and filter, New spark plugs and wires. Now it is running really rough. Idles really low and rough and almost stalls out when pressing the gas. CEL on with cylinder 7 misfire and bank 2 system too lean codes. Any advice

Put some Gumout with Regane on the label in the gas.
