Why do mechanics in Nigeria and Africa as a whole ignore fuel trim data. Meanwhile it is an invaluable diagnostics data. U will see many of them with high end scan tools but all they can do is to scan for fault codes.

Before fuel tream data can be read, u have to understand what is called repair manual which gives the direction on how to use a data list provided by the ECU of the vehicle you are scanning. Many of Nigerian automobile mechanics does not have this to use and dats what is affecting our cars of nowadays. Take your cars to professionals who knows this things and that can explain in details for you. I rest my Case.
