Ok so I just purchased this car and put headers and full exhaust on it.when I’m driving the car and alternator is charging (hair over 14volts) I have no issues. Once alternator cuts off (12-13 volts) tach begins to jump on decel and around 3800 rpms. Now since it works when alternator is on I know it’s not a bad ground. My question is how can I make the alternator continuesly charge. Or what will resolve my issue?
