Okay, i just bought an 01 Wrangler on Saturday. It was just too good of a deal to pass up and is in exceptional condition (since it's never been off road and garage kept). I started it today and my check engine light came on. I did the key trick and the codes that pulled up in the dash were P0136, P0141 and P0161.
I did all the searches and found a lot of info that helped me with the original problem. From what I gathered it is a problem with my Oxygen sensor(s). It looks like I need to replace both of the oxygen sensors downstream on the front and rear of the manifold. Hopefully that makes sense.
So once i figured that out i went to Advance Auto since they are right down the street from to see if they have the parts i need. It looks like i need Bosch part #13687 and part #13691. I can get the first part easy but the second one is supposedly discontinued according to Advance
So i decided to look online to see what i came up with. I searched and found a site that supposedly has it but once i put it in my cart it actually changes the part number to #13687.
So the question i have is are part #13687 and #13691 interchangeable? I pulled the connectors apart tonight and they look the same, so am i missing something or am i just an idiot?
