96 rough idle
I have a 96 4.0 auto 4x4 175xxxmi. I have already done a full tune up and cleaned throttle body. Problem: when ever im in gear stoped it starts to idle rough and the whole jeep shakes kinda bad and it only gets worse the longer im stopped the rpm sits around 600-500. But when I start to drive again it smoothes out. But I will have some serious power loss if I have sat for to long. I have cleaned the IAC but it doesn't seem to be the problem. Also no codes are are being tripped. Anyone have any ideas or have the same problem?

That's correct! Check out rockauto.com. They have the best price I've seen for the brand o2 that came from the factory (NTK). I'd suggest doing that.

rough idle
just yesterday I found the 3 wire sensor that is in the distributor on my 99 .....where it goes into the dist body had all 3 wires exposed. Very hard to see until I pulled it out. I changed that and it took away my rough Idle that has been a problem since I rebuilt......now runs great
