Designed to meet or exceed OEM specifications, this replacement motor restores proper idle speed control, cold-start performance, and throttle response when replacing a worn or failed idle air control valve.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with Holley 90mm, 95mm, and 105mm throttle bodies as well as Sniper EFI 85mm, 90mm, 92mm, and 102mm throttle bodies, the Holley 543-34 IAC motor installs directly onto the throttle body without modification. It also serves as a direct replacement for GM OE part number 17113598, making it an excellent choice for LS engine swaps, custom EFI builds, and routine

(IAC) motor do?\u003c\/h3\u003e\n\n\u003cp\u003eThe IAC motor regulates airflow around the throttle blade when your foot is off the accelerator. This allows the ECU to maintain a stable idle during cold starts, when the air conditioning cycles on, or whenever engine load changes.\u003c\/p\u003e\n\n\u003ch3\u003eWhat are the symptoms of a bad IAC motor?\u003c\/h3\u003e\n\n\u003cp\u003eA failing IAC motor can cause rough idle, stalling, fluctuating idle speed, difficult cold starts, or an engine that idles too high or too low.\u003c\/p\u003e\n\n\u003ch3\u003eIs this a direct replacement?\u003c\/h3\u003e\n\n\u003cp\u003eYes. The Holley 543-34 is designed as a direct replacement for compatible Holley and Sniper EFI throttle bodies and also replaces GM OE part number 17113598.\u003c\/p\u003e\n\n\u003ch3\u003eDoes this fit drive-by-wire throttle bodies?\u003c\/h3\u003e\n\n\u003cp\u003eNo. This IAC motor is only used on cable-operated throttle bodies equipped with an Idle Air Control valve.
