Old O2 sensors, even if not throwing a code, can decrease fuel economy, Old CATS, too. Try using fuel injector cleaner in every fuel up for a while. Take off air intake and try to look at your throttle body for dirt and gunk. Spray with carb cleaner, add new air filter, PVC valve, fuel filter. Throwing out these thoughts.
Early in thread it was mentioned ToyoMasters, Chris, new location a block away from where he has been. Now on Jefferson, sharing a garage with another auto shop.
Chris is honest, and I have never had one issue with his work. He is Toyota specific.
