What is your question?
Its a 1991 Oldsmobile 98 Regency-Elite with 3.8L GM 3800 engine; Every Brake Line Needed Replacement, the Check Engine Light and ABS Light is Illuminated. So first I replaced every single brake line and I mean every brake line, I also replaced the front Calipers, Pads, Rotors and Rubber Brake Hoses; I also replaced the Drums, Shoes & Hardware, and Wheel Cylinders and did a full brake flush with the BG machine. This thing stops on a dime. So then I used my nice GM Tech 1 and scanned the ECM and Chassis for codes. I received as follows 41 - Cam Sensor, 42- Ignition Module, 65 - Oxygen Sensor Detect Running Rich ABS Code A031 - Right Rear Speed Sensor Circuit Open. So I replaced the Cam Sensor, Ignition Module and Ignition Coil, Oxygen Sensor, and Right Rear Wheel Hub and Bearing with the ABS Sensor. Started the car both lights still illuminated so I scanned the car again ECM codes for the Cam Sensor and Ignition Module were gone but still pulled code 65, also ABS Light still has code?
What makes this problem better or worse?
Car Seems To Run Fine But Dash Lights Still Illuminated
How long has your 1991 Oldsmobile 98 had this problem?
Since I bought the car 2 weeks ago

Check wiring and connector to ABS speed sensor - possibly damaged during brake system repair. Rich exhaust has multiple possibilities - mass air flow sensor out of range is a very good place to start.. Good luck!
