The dealer is far from my house so I took it to a local shop. 5 different codes came up. P0125-coolant temp. P0330-knock sensor. 2circuit bank 1. P1130. A/F sensor. (Bank 1 sensor 1). P1150. A/F sensor. ( bank 2 sensor 1). P0171. System too lean (bank 1). I hope I'll just have to change the 2 A/F sensors. Will that that fix the P0171 code as well? The knock sensor is labor intense. I hope it's not that. I'm not sure about the P0125. The car seems to b running at normal temp conditions. Thanks for your advise.
