Ok GMMerlin, here's what I've got. I performed the compression test as you advised and here are the results. I will format this in firing order. 1) 160, 2) 162, 3) 170, 4) 171, 5) 165, 6) 160, 7) 165, 8)172. I consistently used 5 rotations of the motor to produce these results and ran each cylinder multiple times. I used a video camera as I was performing this by myself and it appears the psi is building consistently with each stroke. I ran the test 3 times per cylinder and without posting all results, they were always close. Only a difference of 1 to 2 psi per cylinder with each test. What are you thoughts here?
As far as the vacuum goes, I need to know where I place the gauge. Is it anywhere in line or is there a particular point that I need to place it?
As always, I appreciate your input and help.
As a sidebar, I went ahead and replaced all plugs, wires, coil, module, rotor button and cap.
Thanks!
