O2 sensor????

i have an 88 cerokee and for the past 2 days almost everytime i start it, it runs like its out of gas. I'll even try to give it gas and the rpm's stay around 900-1000. It also sounds choppy..i was thinking it was a O2 sensor or crankshaft sensor..

please help mee,
jmart

My 87 doesn't have the o2 sensor working right now. Its snapped in half, and dangling down by my front diff.

It runs fine.
