Dear customer, regarding the faulty sensors, did you check them? Are the connections of these sensors correct?

Customer: replied 18 days ago.
are correct
Customer: replied 18 days ago.
this is all you can tell me?
Expert:  sebastian manrique replied 18 days ago.

Dear customer from the fault codes there is a possibility that you have problems with the injectors, the engine timing system and the throttle body, I am not concerned about the oxygen sensor as irregular combustion does not necessarily mean that the vehicle has a damaged oxygen sensor. My recommendation is to start by checking the injectors, then disassemble the throttle body and check for excess dirt, if the fault code persists you may need to consider replacing the throttle body. You will need to check the engine timing as there are problems with both the timing sensors and the belt.
