Whenever I'm giving it some gas and just barely creeping along, my car kicks and sputters a little, usually not too bad, but uphill its kicks and sputters pretty good between 500-1500 rpm. I have an automatic, and it does this in all gears.

Anyone know why?

 

Miss somewhere. Bad/weak/no spark. Bad EGR.

 

A full tune-up would probally help: plugs, wires(?), reset ecm, and top it off with a bottle of Seafoam.

 

It has new plugs and wires, but the ecm could use a reset.......i know it does run rich.
