Gonna need to tell us a little more about your car/motor. Sounds like the motor isn't getting enough gas.....you still using the stock fuel pump?

Check your fuel pressure if you can 
I had a (Edelbrock Victor w/bottom feed), and I could not get the pump from leaking (Pressure even checked out OK?). I put in a Holley VolumeMax 170gph yesterday, and - oh my- I picked up 100HP, and I can now go over 5000RPM's. It used to stumble when I first started it up, and blipped the gas. After the Holley no more stumbles.
Run your hand along all the fitting, bottom of the pump and smell for gas. Double check you have proper pressure at the carb. To little or to much will kill it. The only thing I can assume is that with a leaky pump it's sucking up air, which was killing me.
I hope it turns out to be something simple like this.
Good Luck,
Ron

well i got new accel plugs today, still wont go no were\sputtering when i floor it,but when i floor the gas pedal at a certain point ,the car moves, im coming to think that this could be my carb since its dirty from backfiring with the dis. 180* of the week before. the fuel pump seams fine, i dont feel no air suction, everything looks good.i might have to change the sending line hose since it is a little short and has a little bend in it goin into the fuel pump. if this still does the same problem im givin the car away
