Can throttle body cause rough idle?
If your car runs rough when idling, the cause just might be a dirty throttle body. The throttle body controls the amount of air the engine takes in, and when it gets dirty, the engine can't idle smoothly.
What are the symptoms of a dirty throttle body?
When the throttle body gets dirty, it has a direct effect on how smoothly the engine operates. Signs indicating a problem include rough idling, jumpy or sluggish acceleration, poor fuel economy, and stalling. With the use of a throttle body cleaning product, the dirt and debris buildup are easily removed.
Can a dirty air filter cause throttle body problems?

What does the pedal do on a throttle?
The pedal simply provides an electronic signal, telling the throttle body how much acceleration you’re requesting. A motor and gear reduction set inside the throttle body opens and closes the throttle plate to accomplish your request. Over time, carbon buildup can accumulate around the throttle plate, changing it’s “home” position.
