| 2007 Chevrolet Express 1500 4.3L MIL Lamp on VIN: 1GCFG15XX7 P0430: Catalyst System Low Efficiency (Bank 2). 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... |
