EGR Valve location

Does anyone know where I can find the EGR Valve on my 98 Windstar? We are working on it right now and I don't have my haynes book with me. I wanted to just clean it instead of replacing it.

The valve is located directly below the TPS (Throttle Position Sensor) where the air intake tube and the intake plenum meet. Usually the problem with these is the diaphragm develops a leak and they cease to function (operated via engine vacuum). I don't think cleaning will help, but it won't hurt either. A new EGR valve would be the route to take if that is the culprit.

I am also working on my 98 windstar EGR Valve. will try to clean it or replace it. I got new EGR at autozone for 35 bucks with 3 months warranty.

Any suggestions are welcome
