1997 2.3 2wd 5 speed

I cleaned my maf and checked everything i can think of. Please check out my video showing what i did to try and cure it. I’m getting P0171 code.

The fuel pump, sender, snorkel hose and inlet to the tank, fuel filter, and metal solenoid on the charcoal canister has been replaced.

This vid should explain where I’m at. Everything runs well, no problems. Maybe just a slight miss at idle, but nothing really noteable.
