asked by on

My car is throwing misfire fuel cut of codes on cylinder 4 5 6. causing rough idle and loss of power

My car has 180000 miles.
My car has a manual transmission.

Check the harness to the fuel injectors to the cylinders 4, 5, and 6. There could be a loose connection or the injectors could have failed. Put a noid light on each injector and see if there is power to the injector. If there is power to the injectors, then the fuel injectors need replaced. If there is no power, then there could be an issue with the engine harness. If you need further assistance with your check engine light, then seek out a professional, such as one from Your Mechanic, to help you.
