What is a good way to tell which cylinder is missing when the tester says there is spark to each cylinder.
I just changed out the rocker arm assembly and push rods. It is still making a lot of top end noise and is missing on at least one or two cylinders. The spark plug wire tester indicates spark getting to each cylinder. It has a coil pack so I don't know if it is safe to disconnect the spark plug wires to try to find the missing cylinders.
