I have an LS motor in a 92 civic hatch, My fuel pressure regulator line use to come off and then my car would run horribly until the line was put back...then sometimes it would do the same thing when the line was on and the more gas I would give it the more it would putter and almost stall. I stop and let it idle for a minute and then it would be fine... anybody know what this problem could be caused by? It hasn't happened in a while which means it somehow fixed itself-I AM CONFUSED
