I had a hole in the exhaust and i received the following errors:
P0130 - O2 Sensor Circuit Malfunction (Bank 1 Sensor 1)
and
P0170 - Fuel Trim Malfunction (Bank 1)
after i fixed the hole (brand new exhaust before 6 months ago) i received only P0170.
Now i receive both of them again!
I didn't check for a new hole but a don't think so.
I have also high levels of HC (Hydrocarbon) at exhaust emissions...
Is there any idea what to look?
injectors? O2 sensor? Catalytic converter maybe? or any other engine sensor?
