Just to keep this thread full of useful insight. I took out my gal for a spin last night, after being parked for well over a month. She had a horrible time getting past 5000 rpm. Two months before at a track day she screamed to 6500 with NO hesitation.
Certain things come to mind, as I did not change anything:
1) Ethanol, ethanol. I wonder if the gas is going south after sitting for well over a month.
2) I had a very low battery after sitting for so long, car barely started, and I noticed that my amp gage was reading very positive which to me means the alternator trying to charge the nearly dead battery back up. That low voltage may have been hurting my pertronix output
What I am going to do to try to solve this.
First the easy stuff. Check timing (that solved all my revving problems before)
Second, tune up, new plugs, cap/rotor, fuel filter
Third 60 amp alternator upgrade from MSA
Fourth, Fill up with fresh ethanol free gas
I will let you know of the results
if I keep putting these small projects in front of my tranny swap I will never get it done. But that is how these things happen
