Re: my jeep blows black smoke and doesnt idle right..

The check engine light will come on. If it starts to run normal plug the sensor back in while its running if it starts to run worse I would bet that the O2 sensor is stuck either rich or lean. This could be confirmed with a scan tool capable of live data.

If it doesn't change anything than we'll try plan B!
