Alright guys I probably should've posted a while back but I've been pretty busy... so about 2 wks ago on a friday I drive my car home and the car starts up and idles rough, then it revs to about a 3k and it stalled. It's an 02 GTP but I tried to bend the relay to bypass the resistor anyway... didn't work. It would crank and idle roughly till it just wouldn't start anymore. Later that weekend I got in the car and all the lights were out... so a dead battery. I left it like this for a week (it's been a busy week), so last weekend I jumped it, it started and idled rough but once I turned it off it wouldn't turn on again and the lights dimmed again... so I replaced the battery and well now it just does this (I linked the video below) ... what the hell?
