O2 sensor

[irupp33]

I have a 93 rodeo v6 5spd. My O2 light is on on my dash. Does that mean its bad or just a loose connection? Also would this cause any worse gas milage or any power loss?

It means you have logged some multiple of 90,000 miles. Every 90K miles that light comes on, you have to remove the instrument cluster to reset it... 90K miles later -> repeat. Have you noticed poor mileage or performance? Depending on how long it's been since you have replaced the O2 sensor (if ever) it may very well coincide with being time to get a new one.

Well it just seems slow. Granted I do have 23" rims on it. It just seems like it doesnt have the pickup that it used to. Yes the truck has around 95k on it. How exactly do you reset it?
