I have a 01 mustang gt and I am having an issue of my lights flickering.. All th lights flicker when it is running it is not causing any other problem that I can tell of. Just very annoying that my lights are flickering..
Uber stereo? Are the battery terminals clean and tight? Consider having the alternator tested for correct output and excessive AC ripple. Most auto parts stores will do it for free.
I have no system so that wouldn't be the cause.I will have the alternator tested and get back with you.. Thanks for the help this has me cOmpletly baffled
I had the same issue recently. It was the alternator. A guy actually followed me home one night to tell me my taillights were flickering at idle. I already knew it because all my lights including the dash lights were doing the same thing.
