Fuel smell in the exhaust

Hi and thanks for using Overdrive

They would have had to remove the exhaust system. Check and confirm that the oxygen sensors are connected and the wiring isn't damaged.

I attached 3 pictures to help you locate the sensors. Check all of them.

Note: If the check engine light is staying on while the engine is running, you need to have the computer scanned to determine the diagnostic trouble code. Here is a quick video that shows how it is done:

Here are a couple links that describe what an oxygen sensor does and how one is replaced:

Also, I would like you to check one more thing if the sensors are good. The engine coolant temperature sensor can be causing issues and I feel confident that it was disconnected too. The last picture I attached shows its location. Make sure it is connected and there is no wiring damage.Take a look through these links for symptoms and how one is replaced.
