07 Ford F-150 fx4 5.4

Any thoughts? Im pretty sure it's a miss in the engine. When driving the engine seems to be fine but when you step in the throttle it spits and sputters. There is no cel/no code. I am a mechanic but if anyone can think of anything let me know. Thanks in advance.

Start with changing the spark plugs if they have more than 60k on them. Throw a bottle of Techron in the gas.
