just bought myself a snap on scanner nothing fancy just the mt2500 with obd11 global, rover ,peugeot ,opel vag ford cartridges very good tho was looking at the voltages of the 02 sensor at idle with engine at norm temp these are some of the readings i got 02 voltage bank 1 sensor 1 0.260 0.800 0.070 0.350 0.115 0.720 0.095 0.725 0.710 0.280 0.730 0.790 0.265 0.840 0.460 0.645 timing the changes between changes was about 3 seconds does this look normal also would there be any live data info that would point towards a faulty coil pack?
