Pontiac Grand Prix Throttle Body
The Throttle Body of automobiles particularly the Pontiac Grand Prix is an important part that assists in the regulation of air intake within the engine depending on the throttle command of the driver. Located upstream of the intake manifold yet downstream of the air cleaner lies the throttle body which incorporates a butterfly valve, which has the responsibility to regulate the stream of air into the engine. Older model Eco's outfitted with both a Throttle Body Injection (TBI) system and a multi-port fuel injection system with separate fuel delivery, differing from modern automobiles. Mechanical linkages have been replaced by Electronic Throttle Control (ETC) commonly because of its superiority in correlations with other safety-related systems. Some problems that may be solved with throttle bodies are rough idle or stalling of the car and for that the throttle bodies can be cleaned or replaced for better engine performance and fuel economy.
Each OEM Pontiac Grand Prix Throttle Body we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
Pontiac Grand Prix Throttle Body Parts Questions & Experts Answers
- Q: How can you detect and fix a vacuum leak at the bottom of the throttle body on Pontiac Grand Prix?A: The TBI throttle body is attached to the top of the intake manifold by two bolts. They can sometimes work loose from vibration and temperature changes during normal engine operation, causing a vacuum leak. If you suspect a vacuum leak at the bottom of the throttle body, use a rubber hose as a stethoscope. Start the engine and place one end of the hose next to your ear as you probe around the base of the throttle body with the other end. You will hear a hissing sound if a leak exists, but be careful of hot and moving engine components. Remove the air cleaner assembly. Locate the throttle body mounting bolts. Determine if any special tools or adapters will be necessary to tighten them. Tighten the bolts securely and evenly. Do not overtighten them, as the manifold threads could strip. If, after properly tightening the bolts, a vacuum leak still exists, the throttle body must be removed and a new gasket installed. After tightening the fasteners, reinstall the air cleaner and return all hoses to their original positions.
