Engine Performance problem
1988 Other Mercedes Benz Models 6 cyl Two Wheel Drive Automatic 188789 miles
on my 300e it takes a while before I can gain speed, from a dead stop it take a couple of minutes to get up to 40 mph, and I can not press the pedal to the floor or I will loose speed. While on an incline what ever speed I am traveliing at slowly decreases.I can sometimes pump it and gain speed quicker, however it does not go over 75 mph. Any suggestions that I may be able to check and repair?
