Done an error code check on a vn,and came back as code 13 (oxygen sensor),we replaced it and still have the same problem + check engine light is on after about 10 minutes,any ideas on what it could be?.
check the wiring. Mine does everyday bottoming out on my driveway. In and out.
Reset the computer
Check the hole in the collector and see if its rusty, the 02 sensors earth out through the collector and if its rusty can disrupt the connection.
