Does Lucas Fuel Injector Cleaner clean your throttle body@also,does it harm anything?

Fuel injector cleaner is intended to clear out clogged fuel injectors. Fuel injected vehicles do not use a carb. Furthermore, the product is emptied into your gas tank.

It then travels through the fuel pump, fuel lines, fuel filter, fuel rail, and fuel injectors before being sprayed into the combustion chambers. It never enters the intake track before the throttle body (unless you have some kind of aftermarket setup with an extra injector before the throttle body, like a nitrous setup). Even if it did, it wouldn't really do anything for the throttle body.

It doesn't harm the O2 sensor either if used in the appropriate portions and time intervals. The throttle body is most likely not dirty to the point where it would affect performance. You can attempt to use fuel injector cleaner (or fuel system cleaner) additives in the fuel system.
