Engine Performance problem
1984 Mercedes Benz 500sel V8 Two Wheel Drive Automatic 251000 miles
After engine warms up engine misses badly at low (under 750-850) RPM. At speed car runs beautifully with good power and acceleration.
Mechanic tells me coil is putting very high voltage(?) Because plug wires and distributer cap/rotor causing too much resistance. I have had this car from 138,000 miles to now 251000 miles and have never changed plug wires.
