Another FJ62 question... Background: Just finished reassembling FJ62(cylinderhead) that I bought in pieces so no idea on previous history)

My FJ62 now periodically sets trouble codes 25 and 26.(O2 sensor lean and rich) never independant of one another, they are always paired together and I cant seem to figure out why, but I did add some EFI fuel system cleaner in the tank for its first fill up, before the symptoms arose... Is this indicative of any problem or ECM fault?

Next question:
Power Windows only work at each respective door switch, not the master on the drivers door. The window lock button is broken, so my question: Does the window lock button in either position prevent the windows from being operated by the driver door switch(drivers front operates fine from master switch) while allowing operation at the local door switches?

Last question: A/C seems to blow reasonably cold, just evacutated and recharged, no leaks, functionally fine and suction/discharge pressures are good, just seems that the A/C computer/amplifier likes to kick the compressor off at a temp that is a touch too high. FJ60s can adjust the temp the computer looks for with the rehostat, but no such luck with the FJ62 as there are no adjustments. Has anyone run into this issue and solved it?


Thanks for the help!!!
 
I can only answer one of your questions. the O2 sensors need to be changed especially if you think that they are the original ones. there are two and most poeple on this board had good experience with www.oxygensensors.com . Get the the direct plug that does not require any splicing. I believe I wrote something about O2 removal tips on a thread you can do a search. Tell us how much better your car runs afterwards.
 
Btw, I don't think the fuel cleaner affected things. My reason for changing the sensors was that I was getting the check engine code going off when the truck went over 55 MPH. I got the same codes you got. Changed the original O2 sensors that had 200k on them. Never had a code occur since.good luck.
