i have an 04 Gt and i have been having what i belive to be electrical problems. once in awhile when im driving the car will sputter and the gauges will be reading wrong, and it will almost die, then shoot forward and almost die again and so on. i will stop, turn off the car, then start it again and it will go away. it often does this after multiple tries to start up too. i have a reprogrammed PCM, but i added that after the first symptoms of this problem. ive also heard it could be a fuel filter problem? anyone with any advice on how to fix this would be a big help.
