Permanent misfire in number three cylinder. New plugs, wires, injectors. Cylinder pressure is 140 PSI. Leak down test is less than five percent. A colleague advised to complete a running compression check. Flooring the accelerator with no substantial increase in cylinder pressure would indicate a lower engine failure such as a sticking push rod or rounded cam lobe. Is this correct? I have never heard of a running compression check. Thanks for taking the time!
have the same problem?
