I’ve been spending hours trying to resolve a rough idle and multiple O2 sensor codes on my 2000 TJ (po132, po135, po138, po141). I’ve replaced all the sensors I can (the o2 sensors themselves, the IAC, the TPS, PCV, and cleaned the MAP. I’m now down to the cats…
I have what appears to be an early 2000 TJ. I have o2 sensors just forward and just after the cat that sits above the skid plate.
I also have had two o2 sensors on the precats that’s go nowhere, closer to the intake manifold… which is- I assume- because this part of the system is from a “later 2000.”
From what I’ve read there are early and later 2000 model year runs, with one of the differences being the exhaust.
Can someone educate me on what I need to purchase to replace my cat system from the intake manifold to the muffler? Parts websites don’t seem to know the difference between early and later 2000 TJs.
Help?
