Your code is refering to insufficent EGR flow. You have a exhaust gas recirculator (EGR) what lets in exhaust air into your intake when you are driving, but shuts when you are idling. The code means the computer atleast thinks it is not letting in flow. If could be actually working, but the computer thinks it isnt, and correcting the fuel air ratio accordingly. You could then be running lean at high speeds, hence the lack of power. Pull the EGR and check its operation (with a vaccum pump) and for clogs. Other causes to the system could be the solenoid or the DFPE sensor. The DFPE sensor is a common part to fail on the ranger and is easy to find and replace. Check all three. A common cause of many problems, and ones like these, are vaccum lines. Check them to make sure they are in good shape.
