Would it hesitate hard like that if I was a tooth seeing how it idles great?Well, with Schurkey on this one, fuel is good, you say sensors good, no vacuum leaks, etc so leaning towards ignition. Proper dist. installation, not 2 or 3 teeth off, no cracked porcelains on plugs, wires not shorting though jackets or boots, the fact that ignition and pick up coils can't be ohms tested and determined good.
Some new replacement stuff only last 2 or so years etc. As per Schurkey, is the advance coming in?.
