Need some help with HP tuners, Car is running wierd on bank 2 Ok guys, i have been doing my own tuning for awhile now, with the help of a buddy. Well i dont want to keep asking him a billion questions, and i would like a collective input on it anyways.
Lastnight my ca stating missing at idle, and under light accel but not moderate/wot. Pulled 2 plugs and they were BLACK. My A/F guage is in the driver side collector, and driver side is running pretty good i think. SO i was confused for a moment untill i remembered my wideband is in the driverside only. I hooked up hp tuners and my LTFT`s were way off on bank 2 (passenger). SO i logged it for awhile, please see the attached log titled : Cruise Log.
Drove it for half our that way and stayed the same, went to work and logged it again, but this time it was running decent. Please see : Cruise Log 2
So wtf, bank 2 O2 sensor going bad??
Also, tune is attached if someone would like to look at it. Thanks!
