On fuel-injected models, the throttle body controls how much air enters the engine and the injector adds fuel to match. Sensors report throttle position, pressure and temperature so the system can adjust.\u003c\/p\u003e\u003cp\u003eSeals, O-rings, screws and small brackets hold everything in place. If one leaks or loosens, the engine can pull in extra air and run poorly.\u003c\/p\u003e\n\u003ch2\u003eCommon Problems\u003c\/h2\u003e\n\u003cp\u003eRough idle, stalling when you close the throttle, hesitation off idle and hard starting are the usual signs.
