I'm at my wits end

Ok this spring my car was in the garage for about 1 year and a half so far I changed the battery , alternator, belt, plugs , changed the fuel filter, checked everything for a nice simple inspection so she fired up and idled fine so I went for a test drive and and backing out of my driveway I noticed it was idling low then in gear OD I pulled down the street and she starts popping like a popcorn machine my AF was all over the place starving for gas I gave it gas then running rich and more popping yet no codes were thrown at me no knock !!!! So guys is it time for new wires and a good tune I've been putting 93 Sunoco and injector cleaner in it and it seems my gas mileage is like 5 to the gallon and I have a new pump and sender unit and a year old set of 60lb injectors so guys any advice or had similar problems?

Scanmaster numbers? Fuel pressure rising 1:1 with boost? Stock MAF?

Probably gummed up injectors.

Sorry to ask, but during that test drive did you change out the old fuel for new?
