Questionmy 1980 450 sl is running sluggish. It will start fine and i have to let it warm up before i can start driving it. But the acceleration is sluggish and if i drive to a small hill i have the gas pedal all the way down. Any recomendation is appreciated.. The car only have 72000 miles on the car.
Answeryour car should have a K jet injection system. The common causes for poor power are
worn out or out of adjustment settings - timing, spark plugs, dwell, air fuel ratios, worn distributor cap, plug wires ect. Age is the issue on many items , not just mielage
also if your control pressure is high it will limit the travel of the control plunger which means less gas to the engine.
Old , or restricted injectors can also be a cause
What is the service history? Any recent work, how long have the symptoms been present?
K jets can be complicated and must be checked one system at a time
Let me know more information
