Seems like my days off are there to fix my daughters Jeep!

Isnt 1,700 RPM Cold Idle a Problem?

The IAC was cleaned 2 months ago. It ran good fr a while. Im thinking of changing it. I dont know how old the oxygen sensors are. Im about to put my OTC scanner on. Ill be looking at all the sensors as best I can.

I hate to use the Parts cannon! Please Help!

1700 rpm is too high, go ahead & replace the IAC & then see how it runs.

Ok, so I had a hard time getting the bad 02 sensor out (bank 2,2). My 30yr old KD socket was slipping so I had to get a 22mm combo wrench to pry it out.
The 02 sensor readings look normal now.

Q: Do I need to pull the battery cable off to start the relearn process?

I didnt have time to replace the IAC. Maybe tomorrow. The RPMs went up to 1500 rpms then came down on warm up. ll try it again later.

did anybody see any other problems with my recorded reading?

thanks for the help!

When I replaced my IAC all I did was remove both terminals for 10 minutes, and all was good. My initial idle is about 1100 rpm when it is just above freezing 5c outside.
