Installed the 1zz throttle body - - Toyota Yaris Forums

Seeing its a larger throttle body. Say the computer needs to open the throttle 10 percent to let in a certain amount of air. With a larger throttle 10 percent is really like 25 percent. Which is why you will always have a high idle. But why you also get better throttle response and power. Because say you want to open the throttle to 50 percent normall its more like 75 percent if you compare the amount of air being sucked into the engine.

I would not attempt this mod till you have exhausted other possiblities of increasing power such as a AFE intake or trd exhause or headers. Before slapping on the throttle body.
