1969 Dodge Dart Engine Stutter

Ok, So I conducted step 4.
At idle it reads 13.93
At cruise it read 15.61 +- 5.

This was tested with a dead battery. I had to jump it before I got these measurements.
Sounds like you have a non functioning or bad VR. Do what I said above ^ and put everything back together and retest with everything hooked up normal.
