A-Premium Idle Air Control (IAC) + Throttle Position Sensor (TPS) Kit — Direct-Fit for GM Trucks & SUVs, Includes O-Rings and Hard

The A-Premium Idle Air Control (IAC) valve paired with the Throttle Position Sensor (TPS) is a direct-fit replacement kit designed to restore stable idle control, throttle feedback, and drivability on many Chevrolet, GMC, and compatible GM vehicles from the mid-1990s to the 2000s.

If your truck shows rough idle, stalling at stops, erratic RPM changes, or throttle response irregularities, a worn IAC or TPS can often be the cause. This A-Premium kit bundles both components that work together with the engine control module to regulate air bypass and report throttle plate position. Each unit includes the necessary O-rings and mounting hardware for a straightforward swap when the part numbers and terminal configurations match your vehicle.

How will this IAC + TPS kit affect cold starts and idle stability?

Replacing a faulty IAC stabilizes idle speed by properly metering bypass air during cold starts and engine warm-up. The TPS ensures the PCM knows throttle position so it can adjust fueling and idle control accurately. Together they reduce hunting RPMs and help prevent stalls after the engine is started or when accessories engage.

• Idle Air Control valve with 4-pin terminal and 2 mounting holes for secure fit.
• Throttle Position Sensor with 3-pin terminal and 2 mounting holes for accurate feedback.
• Includes O-rings and bolts to simplify installation and ensure a sealed fit.
• Compatibility covers many Chevrolet, GMC, Cadillac, Isuzu, Oldsmobile models (see fitment list).
