just like it says above, when its around 160 it will start to idle around 500 or so, and when i hit the gas it kinda stumbles if i hit it moderatly hard then [ics up and pulls like a raped ape. i orignially thought this to be a sensor problem but have since decelared this out becuase i also have a hard start. if i prime the pump or let it sit till it stops priming my car will start fine on the first go around, somtimes. sometimes it will take 15 seconds of cranking i think this to be either a clogged fuel filter as it did this before the isntalls and it started right after i let the tank go pretty much dry twice. or i beleive this to be a failing pump. any suggestions and tips to point me in the direction would help.

 

no one has any ideas on this? it runs fine once above 1k or even at 800-900.
