    hi so last night i was driving which i havent turned the car on in a few days. the car was literally flickering from interior to exterior lights. unhooked the battery while it was running to see if that was the issue but it wasnt.. alternator sounded like its working overtime though. and my spark plug wires look like ****.

    check your grounds and get the alt tested, just take it to any auto parts store and theyll test it for you

    check the ground on the battery first and look for corrosion on the cables, not 100% sure but follow the battery ground the best you can. i think theres a body ground in the trunk area but im sure

    what other things did you have on, heater blower? wipers? sound system? rolling down windows?
    Anything that might cause an extra load on the charging system.

    sounds like a bad ground, cant see the alt making the lights flash, it may still be going bad. but flickering electronics should be a bad ground.

    on the trans bell housing is 3 grounds, make sure all 3 are clean and tight and not broken off. as well as the battery.

    More than likely your alternator is going bad.. Specifically the internal voltage regulator. Unfortantely the whole alt has to be changed.
