Default Re: Hesitation and slight popping during acceleration? Why?

need more fuel is my guess. running lean? mine was doing that same popping and didnt find out until i hooked up similar to a dyno tune with things in my exhaust reading the air/fuel mixture. my fuel pressure gauge under my hood was broken and i didnt know it. adjusted the fuel pressure (along with burning a chip!) and runs much better. dropped more than .2 off ym 1/4 mile times!
