A-Premium Idle Air Control Valve & Throttle Position Sensor Kit - GM Direct-Fit IAC+TPS, Includes O-Ring & Bolts

If your engine stalls at idle, surges when warming up, or the check engine light flags a related code, replacing the IAC and TPS together can resolve inconsistent idle speed and inaccurate throttle readings. This kit is built to match OE fitment for many Chevrolet, GMC, Cadillac, Pontiac, and performance models from the late 1990s through the early 2000s, delivering a bolt-on installation with the necessary O-ring and mounting hardware.

How will this IAC and TPS replace worn factory parts?

These components are designed to replicate the original geometry and electrical connections so the engine control module receives stable signals. The IAC uses a four-pin metal-body actuator to regulate bypass air, while the TPS provides a three-pin male blade output for throttle angle feedback.

• Direct-fit mounting pattern and connector shapes match factory locations.
• IAC includes O-ring and bolts for a complete install seal.
• TPS uses a bolt-on plastic housing with a round female connector for secure electrical mating.
