If you use the 87 octane gas all the time try using the 89 octane gas or better yet the high octane gas or add some octane booster to the low octane fuel made a big difference for me on gas mileage.

Have you ever tired plugs n wires? Also if it's high mileaged maybe the transmission is a bit tired and running higher rpms then it's supposed to.

I’m waiting on a transmission as we speak to be replaced we’ll see if that helps the situation

More than likely the issue. If you haven't done spark plugs n wires I'd go there.
Replace the downstream o2 sensor. $50 part on amazon. When it fails the engine runs rich.
