I searched and read and searched more for information about the EGR'*. I'm new to superchargers and problems with EGR'*. Here'* my situation

When I start up I have no lights. Boost gauge readys complete vacuum (pegged) until I use touch the gas. Then I see less vacuum. And when WOT (assumption of wide open throttle) it moves into positive boost. After I drive down the street a little on comes the light.

Had the car scanned and it says EGR code. aka bad. Just wanted input/opiniions before spending the $150.

My buddy CFoote said he saw something about cleaning an EGR before attempting replacement.

yup the EGR can be cleaned

My gasket was naturally welded stuck to the valve, so just a heads up.

Newbie Bill, the other guys can confirm this but your boost gauge is working just fine

CFoote (aka Toes to us locals) No wonder I didn't remember what color the car was...look at your pic.

Reading up on EGR one item the computer looks at is vacuum. That'* why I questioned it. Sorry it'* my first Supercharger. And jealousy gets you nada...no help with the walkway either. lol

I have an answer of two letters to your jealousy query: M5

If a non-supercharged car had a boost gauge, it would read vacuum all the time. Instead of them sucking in the air they need, you FORCE in even more. Working just fine.

The digital EGR valve used from 90-93 is easier to clean and get good results. The linear from 94 on doesn't have the same success rate, but I'd still try it first. They're expensive.
