Hey guys! So I had my Jeep sitting for about a week, and after about 10 minutes of letter it idle to get it up to running temp and clear some frost off the inside of my windshield, I started to drive. Well my CEL came on, yet I didn't notice any performance difference in the Jeep. Nothing significant at least. So I took it to my local parts shop and they let me scan it, so I got two codes. p0137 Generic Circuit Low Voltage Bank One Sensor Two p0138 Generic Circuit High Voltage Bank One Sensor Two I've read some stuff about this being one of the sensors for the driver's side Cat. The Jeep seems to maybe been running with a little less power, a bit sluggish, but nothing too crazy. It's always been slow anyway:icon_lol: Anyone have any experience with this? Any advice?
