Spark Plug Wire & Ignition Coil
I have remove this 2 parts from car & trying to test their conditionut how?
The car tend to shake heavily as if, some of the cylinder not firing, depite new spark plugs.
Do you have any misfire codes?What cylinder?
shaking that hard you should have a cel on and the code would show what cylinder or cylinders were misfiring.
Have you check you motor mounts?
With all 4 spark plug wire & 2 coils all out, how do i test them without the need to put back the air intake manifold, throttle actuator, engine wire harness etc back together again.
