I drive a lot and the last month or so I have been getting a faint oil smell in the cab. I have looked over the car extensively and not found any leakage. I do not smell oil in the exhaust and the oil level is unchanged. my mechanic and I looked over it together and he removed a vacuum hose to see if any oil had gotten the air intake. Nothing. When I drove away it had loss of power, Since I was very low on gas, I assumed I pushed it too far and filled up. I barely made it home then I had trouble starting it again. I finally got back to the mechanic and he cleaned up the throttle body and things seamed to be better. we thought it might be the 02 sensor but would wait till the engine light came on. The next day, Saturday, It was not great. started knocking, like too much back pressure or timing and then the engine light finally came on. I had do drive it so I did not push it to the knocking point which did not require too much change in my driving style. The strange part is that my gas mileage went up like crazy. I was getting 22.7 on the hwy and 20 in town. Monday I went back to the mechanic and hooked it up and got a P0420/P0430 code Catalytic converter. We reset the light and the knocking went away. As hard as I tried I could not get it back although the light eventually came back on and my gas mileage went back to 19 and 17. I feel like there is something I am not looking at that is not going to show up on the system diagnostics but is making things malfunction. any ideas
