I got this code on Saturday along with some others like misfire in cylinder 4 and 6. So I replaced the the plugs, wires, and bank 2 sensor 2 oxygen sensor (the one at the bottom of the front header). The cleared the light by disconnecting the battery for a while, all was good for 30 mins or so then the light came back on. I had it checked again and the only sode that returned was P0161. The guy at advance told me to ride it out for a week and see if it goes away and then go from there. But since then the cars idles like its got a like cam and has shut off on me twice while driving. Can anyone help me?
 
If I'm correct, that code means that there is an issue with the voltage on the bank2 sensor 2's heater circuit.

I would make sure they gave you the right sensor. I'm sure they did, but stuff does happen. Make sure the connections are good.

Try moving that sensor to the other bank. If the code changes to bank 1 then that o2 sensor may be faulty. From your description you obviously have the v6.

Yup. I got a 2.5 V6. I guess I can try that this weekend. Any other suggestions?

Not sure bout ur year car, but my 95 has a relay in the engine fuse box specifically for the o2 sensor's heater circuit, I guess that could be a culprit but try moving it first. Like i said, if the code changes to the other bank after you move it, then the o2 sensor is faulty
