...up and dies? I fixed a known problems with the fuel pump connector under the driver seat, and it seem to work for a while but then it began to do it again.


Here are the details,

1. no PCM codes, at the beging it had a code for the evaporator system but after fixing the connector problem it went away.
2. Start up, get going and a while later, most of the time after it is warm it starts to sputer and the RPM goes erratic and some times it even dies. It almost acts like when you run out of gas!!!
3. Some times it happens when you try to punch the gas and go fast, other times it does it even if you are nice to it.

Please help!!!!!!
 
definately sounds like a fuel delivery problem...if you often run on near empty that would confirm it.....maybe look into a fuel line/injector flush...also change your fuel filter...it should be a cheap 5 dollar part
 
If it's a 4 barrel carb, it has a crack in the barrels. Which would cause it to sputter because it would be trying to fire between both barrels at the same time.
