When I come to a stop the headlights flicker a little bit.
If I put it in neutral and rev the engine the flickering stops. What is the cause and is it serious?
Double check your battery cables make sure they are free of corrosion and tight and if it continues you should have a repair shop test your alternator and you can locate a shop here www.repairpal.com/directory
