Cyllinder not getting power, diagnosis?
I have a 2007 lincoln mkz and I have two cyclinders not getting power. I initially thought they were misfiring, but he took the little yellow thing with the positive and negative pokers to it and found out thaty there is just no power getting to those cyllinders. Coils and spark plugs were replaced to no avail. Car sputters while running. Mechanic said something about possibly being a problem with a power modulation chip and sent me to a Ford dealership for reprogramming. Just wanting to make sure that that's the problem before going to the highly expensive Ford dealership in my area.
