Thanks Steve. You can not get too simple for me, I appreciate the thought. I do a lot of "piddling", and get a great joy of being able to do as much myself as I can. Often as not, my work creates more issues than I solve, but I tackle most.
OK now, to be sure, I can check all 4 at the same time, or check all 4, one at a time, engine at idle?
I'm working on a 48 DeSoto, 1st Gen (1958) Chrysler Hemi, 2 4's. Auto tranny (A727TF), mild cam, small stall converter. Although I go to car shows, I always choose not to be judged. It's a driver, and I enjoy the people, the cars, and maybe couple of cold ones.
I just replaced plug wires (MSD 8.5mm,) (plugs (NKG) . Waiting for new coil (MSD Blaster2).
No moparts members near, very rural area, Chevy people up the ying yang.
