I have a 72 olds cutlass. I thought it would be a good idea to put STP cleaner in my gas tank since I filled it up with gas. I don't know if the STP has caused problems, but now my car is running rough and when coming to a stop or slowing down my car shakes like it wants to turn off. If I brake without giving gas my car will shut off. Anyone know what I can do to get my car running right again? Before I put the STP my car ran great, I just thought it would make it run better. Do ya'll think my fuel pump is the problem or my fuel filter??? Thanks in advance. Carlos-
