2007 Chevrolet Express 1500 4.3L MIL Lamp on
Posted to GM Driveability on 11/9/2016 5 Replies

looks like bank 2 convertor can't store oxygen when you snap throttle. if you hold at 1500 rpm for 30 seconds then snap throttle 3 times the o2 sensors do change more than 200mv. just wonder if i replace convertor will it take care of my o2 sensor codes? Thank...
