Question about 1999 Mercedes-Benz S-Class
Posted by Anonymous on
Are all your vacuum lines in good shape and tightly connected? My 95 E320 will start rough if it has a bad vacuum seal on the engine oil fill cap, the gas cap, oil dipstick o-ring, pcv rubber seals in valve cover...there's about 20-some engine vacuum seals on my M104 I-6 Might have luck buying a can of MAF sensor cleaner and clean MAF sensor and clean the air temperature sensor while you're at it, inspect the air temp sensor o-ring too. Could possibly be a failing crank position sensor or something simple as an ovp relay. Hope this helps.

hi you need to take it to the dealer to have it scanned. There is a way to fix it with the buttons on the dash. But you need to know German if not the dealer can fix it and it wont cost much to get it fix. hope this helps

You may also have issues with your air flow meter.Generaly though this symptom is usualy a fuel pressure problem.This test may or may not work depending on wether the fuel rail is the problem or the pump.Squeeze the fuel return line at the back of the fuel rail and if engine improves the fuel pressure regulator on the fuel rail may be faulty.If no improvement its likely the pump.The best and most accurate test would be to use an inline fuel pressure tester.Can you hear the pump pumping up to pressure when you turn the ignition on?Usualy though the pumps fail but can be heard running but unable to maintain pressure.

psi diff inside tank is wrong.
use a OEM fuel cap to make light go off.
make sure it clicks at least 3 times.
