No it's been pretty cool here in FL so I've had the ac off 90% of the time unless I'm on the phone with the windows closed

A belt can be too tight, but normally the belt will just break before it does any harm. Normally...
I believe the 2 main sensors that will really mess up MPG without you really knowing are o2 sensor and engine temperature sensor. Both make the car run rich if not working properly. TPS can as well, but it gives off many signs. You said your dizzy and timing are good. I personally would go with valve adjustment and replace those sensors. They don't always throw codes for some reason. The reason I say valve adjustment, even though you don't hear the valves is because you don't know when it was last done(probably when the motor was assembled by dealer). The least you could do is check the lash. That is very easy to do yourself.

What did you clean it with? Cleaners will make your car run like shit if you spray too much until it burns off.
TB cleaner. I probly didn't let it dry long enough. Only a few minutes.

Thinking about it I wonder of my coolant temp is bad or my thermostat is bad. When it's hot outside it runs at around normal temp. Maybe slightly cooler than normal temp but at night and when it's raining or cool out it stays way cool

could it be a vacuum leak? OR maybe check the wires to the AC mine had a tear and it was causing the same effect.
Also the MAP sensor and TPS connectors check them for fraying or breaks and fix accordingly.
Charcoal canister lines could be disconnected. this fixed somewhat a hesitation issue i had as well.
