Welcome to CF.

I have the same problem on my 99 cherokee 4.0. Its the upstream O2. I have 4 wires...
brown/yellow, green/white and two that look black. I have no idea which goes to what. O2 has two white, gray and black...

Can anyone help!!!!

 

Old thread is old.

Try the grand cherokee section. This is the complete wrong section. BUT... props for using the search function.

It also sounds like you have the wrong O2 sensor.
