Now, regarding o2 sensor, would an O2 sensor affect engine starting at ALL if it is disconnected? One of my o2 sensors are disconnected.. made a mess of it removing the exhaust pipe, now I need a new connector or just cut / short respective wires.. and shield them..


Secondly, what is the stock tyre/rim size for a jeep cherokee?

 

And one more thing, I got new tail lights for my cherokee, as I was fitting them, there was a problem (kind of)...now there are FOUR bulbs..
One is the parking / brake bulb, one is the reverse light, one is the indicator, for what the fourth bulb is for? I have never seen it turn on as well.. :s It was the normal size as the other ones..
