My check engine has been on for a while. It was diagnosed origianally as an CO sensor. I recently had the transmission replaced (used). My car started running really off afterwards. The oil indicator goes to low when I initally start the car, then rises to mid point after a few minutes of running. I took the truck into and the the auto repair shop and the code showed "engine lean" what is engine lean and would the oxg sensor have an impact on it?
