Hi,

My engine management light has come on i have a subaru impreza gx
The light came on 2 days ago i opened the fuel cap and released the air it then went off i think it might have come on because of air pressure, it stayed off but has now come on back i opened again then it went off but now it will not go off at all. any help please. thanks.

 

What year?

 

2003

 

just to add light came on after mot i went in when they were in the middle of emission test they put cloths over exhaust i asked y they needed to do that they said because my exhaust was to big could they have damaged the sensor ... is this something i will need to get fixed will it damage my car if this is the case?
