Ok, first some backdrop. So finally decided to go Stage 1. Absolutely stock besides Cobb stage 1 map. Had new map on for about a week and felt good and strong. No CEL's!! But after updating AP and deciding to connect the green test connectors to reflash the update, i happened to check for codes using the AP. Only then it shows 2 codes: p1152 & p1153. but if i disconnect the green test connectors i have no CEL nor does the AP show any codes what so ever?? Im assuming that my o2 Sensor bank 1, sensor 1 needs to be replaced but any reason why my car wont throw the CEL nor the AP unless the green connectors are connected?
Any and all critisism welcomed!
