Mercedes Benz ML 320 2002
Our car suddenly has no power event I press the gas pedal deep. max only 60-70 Km/hr, and the engine really hesitate every time you want to run faster. Our mechanic just check all from Mechanical and electrical, he told us no problems with mechanical, and he already checked all the electronics attached to the engine no problems. remove the fuel tank too, no problem. Adn all still the same has no power. So next week he want to check the ECU? Is anyone has this problems before, and if the ECU ever has problem for this car ML 320 2002 W163. Thank you if any body can help us.
