car wont rev past 2300rpm...

[jdunbar10]

ok here is my new problem it seems to be one after another...
but im fixing them all one by one


but anyways after rebuilding my motor my car hauls ass but it stutters and boggs out around 2300rpm, once i get past 2300 its nice and smooth and fun as hell

i changed the o2 sensor, maf sensor. spark plugs and wires and nothing... any ideas ###?

Check vaccum lines, make sure they're all hooked up,
