Ok thanks for all the comparisons. For kicks I took the vacuum advance off to see if that would change anything. Not really. My initial is at 23 right now and all in at 35 on timing.
After car warms up idle usually moves 1 to 1.5 points on 02. My cruise does seem to get better as the car warms up, but it fluctuates from 11-13.5 depending on rpm.
I am going to put an ask out on a new thread to see if anyone near me is mechanic near me good at Pontiac tripower tuning to have them take a look as another set of live eyes. As u say, hard to do online. Let’s see. Appreciate all the help guys. And yes maybe the 62 are right.
