Just like the throttle, the throttle body plays a very important part in how your fuel-injected engine runs, and makes the car move. The air intake system relies on the throttle body as a pivotal component. The air intake system is what is responsible for controlling the air flow that passes into your engine. For this reason the engine speed is in fact determined by the throttle body.
It’s always wise to be aware of the signs to watch out for that may indicate it’s time to replace the throttle body. Obviously, if any signs pop up, it’s best to get your vehicle looked at by a professional.
When you are ready to purchase a new throttle body, keep a few things in mind:
Buy new: Make sure you’re purchasing a brand new part, rather than a used one. You need to know that the part is clean and free of dirt and debris, so that it will work as it is meant to.
Review your owners manual: Refer to your owner’s manual regarding your car’s throttle body. This is the best way to determine what you need.
Quality: Be sure to ask about the quality of the parts used in the throttle body. Different price points can provide you with higher or lower quality materials.
Warranty: Ask about the warranty on the part.
