i think i am about to get even more to a tank now
i just replaced the battery and terminals and all the gounds and power wires from the battery
WOW
the car starts much faster and runs much stronger
also the lights on the dash are no longer dimming
there is a ground right uner the battery tray which i thionk was the biggest culprit
it was breaking and slitghtly corroded
time to go back to the dyno
