The heads, throttle body, water pump, ignition coil, and transmission have been changed. I have bad gas mileage. Could it be the injectors?
Do you

Good morning,

I would start with a compression test to be sure the engine has no internal damage.

As far as the injectors, yes, they should be professionally cleaned. Additives have no effect on cleaning.
