Misfire on piston one car engin shake

1 Answer


Check the fuel first, make sure it is gasoline and not water or diesel, then look at the spark plugs, and run a compression test, it may just be time to change the plugs or a valve has stuck open, then ignition coil output, a weak spark can also give a misfire code, then the injectors themselves, dirty injectors can cause a misfire also.
