I need some help with my 96 SE-R. It has 76,000. Latley, the car will shut down when I shift into neutral before stopping at a light. Also, while cruising on the freeway and on the street, the car will begin to stumble and stall, as if was about to shut off, and as soon as I put it into neutral, by the time I reach the stop light, the car will shut off. Seems like either an air or fuel problem. Could it be time to change the O2 sensor? I'm running hotshot headers, if it makes any difference.

Thanks,
Gino
