Engine Performance problem
1991 Mercedes Benz SL500 V8 Two Wheel Drive Automatic 136000 miles
My Mercedes has a problem that when the engine is at running temperature after travelling 20-30 km and you stop and switch the engine off and leave it for more than 30 minutes and then try and start the car it is difficult.
I have to push the accelerator flat and then turn the key to start and after a couple of cranks the engine will ignite but it will run as if it is on 5/7 cylinders and after a short period she would idle normally.
I have had the plugs changed, the injectors cleaned, the over voltage protection relay checked but to no avail.
