[cary]

Ok guys i have a 89 nissan 240sx blacktop. And it spits and spudders when i drive or rev it. Big lack of power when i try to drive it. So i drained the gas out and replaced the fuel fliter and put new gas in and fliter still same prob. Then i thought maybe timing was off so i re timed it still same prob. Checkex the cas ans its work correct . So im thinken maybe the oxygen sensor. Any ideas guys need to get it runing this week
