O2 Sensor issues?
I recently replaced my MAF, entire catalytic converter y pipe, and put in 4 new bosch premium O2 Sensors. The truck is running better than ever (at least since I bought it) but now the infamous SES light has returned and I'm getting the following codes: P0161, P1175, P1172. Any help would be greatly appreciated.
Current Vehicle: 2000 Land Rover Discovery Series II V8 (119k miles)
Previously owned: 1995 Discovery 1 (Miss is dearly)
