1991 300E acceleration problems
My 1991 300E is having acceleration issues. When I put the pedal to the floor, the car accelerates very sluggishly, about the same as when I don't put it down. I had transmission problems with the car (slipping) but fixed that about 500 miles ago. There are 191k miles on the car, and I service it regularly. Does anyone know what could cause this acceleration problem? It also idles at about 1200-1500 rpm with in park and neutral, and about 1000 rpm when in gear.
