Engine is running rich as you can smell it from the exhaust. There is no check engine light or stored codes. It runs just fine with only the very slightest of stumble on idle.
So I am wondering could it be bad O2 sensors while still not throwing an error code? Could it perhaps be an injector(s) sticking open? They are the original injectors with 225k miles. Even possibly a bad coolant temp sensor?
Any help is much appreciated.
