1999 regal 3800.........can anyone tell me where my EGR valve is located? thanx.....JOE

On the LS, its on the driver side back near the firewall. Looks like a metal "mushroom"... hard to miss

What specific EGR related issue are you having? Do you have a diagnostic trouble code (DTC)? If so post it.

Local parts store read the code...said I have a bad EGR valve. On the highway, the engine kind of flutters and shorly after my Service Engine Soon light will come on. Thanx fer reading ...........JOE

You can try cleaning the EGR valve by using carburetor cleaner inside the EGR cavity to clean and loosen the carbon on the back side of the pintel. Keep the EGR inverted so as to not allow the carb cleaner to drain into the electronic solenoids. Let it sit for about 1-hour with the carb cleaner, then use a brass brush to clean under the seat. Pour out the carb cleaner and use brake clean for the final wash, then dry with compressed air. Next, soak the same cavity with PB-Blaster and rotate to allow the penetrate to soak the pintel rod well for about 15-min while moving the pintel back & forth off of the seat with a small screwdriver, then pour the excess out. (do not blow out with air) then reinstall. Total cost less than 5-bucks! :grinyes:
