undefinedundefinedundefined
car now runs once out of 10 attemps. have changed out coil, plugs,both balasts, injectors, wires, cap and rotor, fuel pump and filter. I took out the jet? in the fuel distributor it was clean and looked fine I reused it and after that the car ran but still only on less than all cylinders. HHHEEELLLPPP ME

Have you done a compression test?

Is it a dead miss on the same cylinders, or is it firing on all intermittently?
What did the plugs look like when you changed them?

"76 450sl not running on all cylinders
undefinedundefinedundefined
The plugs are new as is the coil, wires, injectors, cap&rotor , both balist resistors and the fuel pump & filter plus a new warmup regulator. Where sould I go from here? Now when the accelorator is pushed the rpm goes down, if you pump the pedal you can get to higher rpm range. Then if you release the pedal the rpm goes to zero and the car will not restart. Oh yes when thwe car is cold it will start after several trys and only idle at between 1500&2000 rpm.
