Q: Q: Fuel injectors misfiring

asked by on

Fuel injector two and seven are misfiring.

Hello. If you are getting codes for the injectors themselves then they may be electrically failing and in need of replacement. I would typically check their resistance with an ohm meter to verify if they are bad, as a bad connector can cause this also. If the codes are for a misfire on those cylinders, then it may not be the injectors. The spark plugs should also be checked and replaced if needed. If the injectors, spark plugs, and coils are good then a compression test should be done to make sure that the engine does not have an internal failure. If you plan on having this inspected, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your misfiring issue and replace your fuel injector if needed.
