second problem fuel pump?
it seems like my air fuel ratio is all of the sudden off.. it like sputters at stop lights and seems like it wants to stall out quite a bit.. hopefully its something as simple as that... maybe? |

Re: first problem- 1992 saturn
What's the fuel pressure at when it acts up? Any codes in it?

Re: first problem- 1992 saturn
I would check it beofre assuming that it is low, no sense in replacing a good pump.

Re: first problem- 1992 saturn
i decided to put in a higher octane gasoline in my car 89 and it seems to drive a lot better than 87 but when im still its still wants to like stall and shakes my whole car.. it kinda reminds me of the way my dads stratus was acting when we had to replace the fuel filter.. does that sound feasable?
