hey all

I have recently bought an auII xls falcon ute 6 cyl 5 spd manual I have a problem when driving once the ute is warmed up and being driven for a little while it developes this problem when I go to drive take off from lights in 1st change to 2nd and then it doesn't pick up the power for a few seconds and revs don't seem to build if I put the throttle flat to the floor it picks up power I am wondering if it would be starving of fuel or maybe air or something I had throttle body idle speed control motor and throttle position switch replaced and also new throttle cable I am wondering if it isn't getting enough fuel that could be fuel filter but before I got out getting stuff I may not need would like to hear your thoughts and oppinions thanks.
