My 1994 integra smells like un burnt fuel, my friend said that my engine is burning fuel really rich, we checked the iac, it was clogged so we cleaned it, we check the spark plugs, it was used up so I changed it, also changed the valve cover. But I still smell un burnt fuel/gas, whats the cause?

Unburn fuel is Hydrocarbons-check and test the coolant temperature and oxygen sensors, fuel injectors and fuel pressure regulator could be leaking.

This car was inspected before, there were no fuel leaks. My friend said it could be the o2 sensor, but the o2 sensor light is not on
