A-Premium Idle Air Control Valve & Throttle Position Sensor Kit — GM/Isuzu Fit, OEM-style with Hardware

If your engine idles roughly, stalls at low speed, or your throttle position readings are erratic, replacing both the IAC and TPS together can eliminate a common source of driveability issues. This A-Premium kit is built to OEM-style fitment for many Chevrolet, GMC, Cadillac, Isuzu, and Oldsmobile models from the mid‑1990s through the mid‑2000s and includes seals and mounting hardware for a complete installation.

How are the IAC and TPS constructed and what comes in the box?

The kit pairs an idle air control valve and a throttle position sensor built with OEM-style electrical terminals and two-point mounting for each part. Both components include O-rings and the necessary bolts so you can replace them without hunting for extra hardware. Connectors follow the original male/female terminal genders for straightforward wiring.

• IAC: 4-pin terminal, 2 mounting holes, O-ring and bolts included
• TPS: 3-pin terminal, 2 mounting holes, O-ring and bolts included
• Terminal gendering: terminals male, connector housings female for direct fit

What driving issues can this replacement address?

Replacing a worn IAC and TPS can resolve symptoms tied to idle control and throttle position sensing without needing multiple service visits. Expect more consistent idle speed, easier cold starts, and steadier low‑speed operation once properly installed and calibrated. Note that further diagnostics are recommended if problems persist, since vacuum leaks or ECU faults can cause similar symptoms.

• Eliminates erratic or surging idle caused by a faulty IAC
• Restores accurate throttle angle input to improve throttle response
• Reduces stalling during idle or deceleration in compatible models
