Find you vacuum leak first. I would leave the egr alone. It helps lower combustion chamber temperatures. The EGR solinoid only gets vacuum at part throttle cruise from the port on the bottom of the throttle body. The best way to see if the egr is at fault is to disconect the line from the egr valve and atach a vacuum pump and watch to see if the valve moves when vacuum is applied and returns to it closed position when vacuum is released. then try it running at idle. apply vacuum to the egr valve. If the car stalls or get near to stall then the egr is working properly. Plus the egr valve is under the plenum so no one really sees it, so you not really cleaning up anything.
