      I think your 03 is kinda on the high side, especially if it's cool out and not running the A/C. I haven't checked mine in a while but IIRC, it's usually sits around 190-195. I know that below...

      Well think i figured it out... The most recent time i can remember relearning the system was when i cleaned TB and did valve/intake gaskets. My CAT plugged up some time after i did that...

      If you cut the shroud like in said picture does that mean id have clearance to remove fan clutch and fan at once without opening the top of radiator neck? This would be awesome if thats the case.

      STFT and LTFT look to be centered around 0% in this run. Will be interesting to see the comparable logs from your other vehice

      had not seen the pattern in stft? how else do you think the o2 would result in a fluctuation. That can only be caused by a changing fuel input or valve issue. Anyway, IF your stft is not...

      Sounds like security wasn't relearned properly. I've read it can takes multiple times for the relearn to succeed, i would keep relearning until it works - assuming you're following the correct...

      There is a quick 2 - 3 second clip of my 02 sensors at the end of the video. I have rear 02 sensor tuned out as my CAT is gutted. No fuel smell, new air filter and dont believe 03's have a MAF not...
