MERCEDES BENZ 300E BACKFIRE PROBLEM

1990 Mercedes Benz 300e • 153,000 miles

This Merc. Has slow response on Acceleration. I think problem is in fuel Distributor. When I rev. It at Idle or while driving, it will backfire. I took air cleaner off. When I accelerate manually and push down on Vacuum Throttle plate, it will accel, but vac. Plate will not draw down on it's own when accelerating with throttle.
