To be certain, you should:
* Consult your Corvette's repair manual: This will have diagrams and precise location information.
* Use a reliable online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) have diagrams that you can search using your vehicle's year, make, and model. Look for a diagram showing the intake manifold.
It's a good idea to visually inspect the area once you have a better idea of the location from your research, as the valve itself is relatively small and can be difficult to spot at first glance.
