hi, i just recently bought a 180sx. i noticed that when i was driving with lower than half tank, and I would drive around 5 or 6000 rpm in frist or second gear, It would HICUP and like lag. I was thinking maybe a fuel cut off? or what?

when I have a full tank, (always 94 octane), it doesn't do it. it drives normaly.

anyone else with this issue? let me know thax!
