Mechanical noise (knocking) in the engine The possible causes and solutions are as follows.<br \/>\n(1) The connecting rod bearing is damaged. Check the bearing surfaces of the connecting rod bearings and crankshaft. Install new parts if necessary.<br \/>\n(2) The crankshaft is damaged. Replace crankshaft.<br \/>\n(3) Accessory failure.

Fuel consumption is too fast The possible causes and solutions are as follows.<br \/>\n(1) Fuel system leaks. The parts at the leaking place need to be replaced.<br \/>\n(2) Fuel and combustion noise (knocking). Slight increases in fuel consumption may be due to fuel injector failure, engine roughness, or other factors that result in power loss. Refer to the \u201cEngine Misfires or Rough Engine\u201d section and the \u201cEngine Lack of Power\u201d section.<br \/>\n(3) Fuel injection timing error. Adjust fuel injection timing.<br \/>\n(4) The fuel setting is too high.
