hey guys, i was wondering why my car bogs down from idles to 1500.... after i reach 1500 it goes fine, but b4 that even if i floor it ,it wont go anywhere at all, just realllly slow till i hit 1500.. idk what the prob is...any ideas? juss got new egr valve, plugs,wires, coil,tps.iac... still does same thing

 

thats how my car has always been.

dohc?

 

yea its a dohc, but why would it like juss bog down and stuff like its gettin to much or to little fuel? i replaced everything so far on this car, belts,fuel pump, fuel filter, plugs wires, diff injectors and everything.. ughh
