Anybody got a clue what would make this happen? I went to the gas station, filled up, and when I went to leave, my car would not stay lit. If I revved it, it was fine, but as soon as I let off it would sputter down to no rpm's and die. I tried it again, with the same result. Then i tried it a third time, and just rode the gas and left. Hasn't happened since. WTF. I've been toying with the notion of removing the old throttle body and intake manifold and cleaning them. Good idea/bad idea? Any help would be great.
