changed that also. if the pump is low on volume it should show in a psi test correct? it runs good at idal if u try to get into it to fast it cuts out and breaks up but if u drive it normal its fine. kinda of boring. if u stall the converter it will sound good but as soon as u put it to the floor and let off the break it cuts out. the pump that is in the car is used but the one that i had in the car before was new i bought a year ago it was fine till about 5 months ago.so i changed the pump and it acted the same way. i dont understand it put a carb on it and nos bottle and i can work on it. lol thanks again for the help

 

everything in the fuel system is new but the injectors. they r stock oem and the pump i changed with no change in performance the pump that was in the car befor was only a year old.

 

Well Im sure this is real basic but have you checks the air intake for blockages? It could be injectors, but it sounds like its not breathing well (either inhaling or exhaling) Id suggest maybe taking the intake off (the tubing or throttle body) and looking for obstructions. Try running the car like that and see if it feels better. (I had a similiar problem on my old saturn)
