Hello! I have an issue with my Honda Civic EJ9, I went to my mechanic,he cleand my throttle body and changed my oil+filters and after cleaning the throttle body on every cold start the car smells like petrol outside of it and sometimes it has a strong petrol/oil smell while i am driving with my windows down. Does somebody know what could be the issue,is it possible to be running with rich fuel mixture?

your mechanic.
Who knows what he did or did not? He could have forgotten a gasket, he could have smeared some weird cleaning product in the sensors, etc
