Drive the vehicle under the same conditions during which the problem occurred, and look for a block that is out of range.
A restricted fuel filter or low fuel pump output will increase fuel trim under load.
Leaks that allow air into the intake system will result in higher fuel trim values in the idle cells but normal values in the higher speed cells. This is because the air leak is minimal to the engine's total airflow at higher speeds. A bad mass airflow sensor will also affect fuel trim. This is a relatively common problem.
A plugged or sticking fuel injector will affect fuel trim cells equally as rpm increases.
