Sometime when I press the gas it don't move right then, and sometime the car will just cut off.
Do anyone have any suggestions to what might be causing this to happen.

which engine are you using?

Does it bog down before cutting off or just abruptly cut off?

Yeah it bog down and then cut's off, and when I hit the gas it hesitates then it go.

It's a 1/10 exceed truck

Sounds like your needle adjustments are off. Check those out.

def sounds like it is off on the needle adjustments, is it leaned wayy out or waaay in, also check for air leaks in the fuel line/kinks, but it def sounds like a tune issue[>:]
