SUSPECT wide-band O2 sensors. No codes logged but engine runs rough @ idle and lumpy @ cruise.These live data readings were noted:
Inst mix ctrl bank1 @idle=5.5% @crus=2.3to4.7%
Inst mix ctrl bank2 @idle=5.5% @crus=0
Ave mix ctrl bank 1 @idle=3.1% @crus=0.8%
Ave mix ctrl bank 2 @idle=5.5% @crus=0.8%
Sensor 2 bank1 @idle=0v705 @crus=0v335
Sensor 2 bank2 @idle=0v860 @crus=0v505
returning to 1st figures on return to idle except that sensor 2 on each bank appears to be switching. (There are NO volt readings for the wideband sensors)
kit: Axone2000
Does this point to anything?
