ok i got a brain teaser for you guys (or maybe not i suck with cars) im driving on the freeway fine, but once i get on the exit ramp and get to a red light for a few sec., the car rumbles and dies, i start it again just fine, then when i press down the accelerator normally, it barely moves, then jolts like i put it all the way down, then dies again. i start it up again just fine, does the same thing but doesnt die this time, i pull over to a gas station, checked all the fluids and they're ok. i start it up again and it does the same thing again, only now it dies again at another red light, so i start it up,, but at another red light i have one foot on the brake and one foot on the accelerator so that it keeps it from dying, so what am i lookin at here, is it the alternator, fuel filter, spark plugs or what?
