Default 2004 3.7 issues

So the girlfriends truck has been doing some strange things.
When the engine is cold, put in Drive and press the gas, It stutters. Not all the time but alot.
It has done this so bad it has shut off. She says it feels like stalling out a straight drive.

So I did a basic tune up. Oil change, spark plugs and wires, Air filter....

A few weeks later it threw a CEL, I forgot the P Code but it was a fluid pressure sensor or switch in the trans. It has cleared itself, but now she says the MPG has gone way down.

What else can I do? Im a diesel guy... Fuel Filter?? but Advanced and Orielly's doesnt have them bc its an "unserviceable part"
