A parasitic drain is current that continues after the car should be asleep and can discharge a healthy battery. The job is to confirm the battery and charging system first, let the vehicle…

A surging idle on a fuel-injected 1986–1993 Fox Body can come from unmetered air, base mechanical condition, dirty or sticking idle control, throttle-body setup, sensor input, fuel…
