Some drivers only think about the engine when there's a problem, but the power you enjoy from your Toyota 4Runner demands attention. A clogged Toyota 4Runner idle air control valve ruins the effect, though, because it limits the air that the engine needs and often causes the motor to stall out. When you need a high-quality replacement, AutoZone is your one-stop shop.

An incorrect air-to-fuel ratio ruins the efficiency of your engine. When the 4Runner IAC valve gets blocked by debris and carbon, too much fuel floods the motor. That causes your SUV to decelerate instantly when you let off the gas, and the extra gas in the engine causes backfiring. AutoZone offers free battery charging and engine diagnostic testing so identifying the issue is easy, and trustworthy advice provided by helpful staff is available to make sure you're ready to do the repair. You can even shop our online assortment today and benefit from Free Shipping on any purchase of $75 or more.
