What is the 2003 Chevy s10 egr valve location?

The 2003 Chevy S-10 EGR valve is located at the back of the engine above the intake manifold at the top of it. If You notice that Your truck is running rough it can be a problem with the EGR valve being stuck open or closed. The EGR valve is used to help recirculate exhaust gasses into Your engine to increase throttle response. It also is used to help burn off emissions that are in Your exhaust gasses one more time before they go through the exhaust. This can help cut down on pollution levels from Your truck. Usually if Your EGR valve is failing You will get a check engine light at Your dash to let You know of the problem.
