Re: how to clean an egr?
Use carb cleaner, the spray, and q-tips. Just don't get the spray in the diaphragm (stay away from the rubber vacuum lines). The two ports going into the intake from the EGR valve can be completely clogged. Take a small screw driver or probe and pick the carbon out of these. Use some spray between picking. If you can take the EGR off and the car doesn't run any different those ports are clogged. Clean all of the little pipes that might be sticking out from the EGR.
