How It Works

The throttle body is a key part of the fuel injection system, controlling the amount of air entering the engine so the powertrain can maintain the correct air-fuel balance. On affected vehicles, wear or contamination can lead to inconsistent idle quality, reduced acceleration response, and drivability concerns. The SKP SK977360 is engineered as a replacement throttle body for the listed Chevrolet Trailblazer, GMC Envoy, Saab 9-7x, and Isuzu Ascender applications.

Common Issues It Can Address

• Rough or unstable idle
• Delayed throttle response
• Reduced engine performance
• Airflow control faults in the fuel injection system
• Fuel economy loss caused by improper throttle operation

Installation Notes

Verify vehicle fitment by year, make, and model before installation.
