Locating and Cleaning an EGR Valve in my 2000 Chevy Lumina?

You have a EGR code?. Its not that simple. If you have a 3100, you are going to be removing the Intake manifold and digging, scraping and maybe even drilling out the carbon deposits that are the root cause of the EGR system not working. Thats normally the problem. the valve is right next to the Throttle body. Three rusty bolts hold it on and a 5 wire flat connector on top. Cleaning the valve wont be much more than knocking out a piece of carbon thats got the pintle stuck open. But those chunks are coming from loss build up thats breaking free from the intake port.
