I have a 98 ranger 2.5l 4 cylinder.

When I go to 4 gear down side streets to save gas my truck vibrates a lot when I give it gas. Someone told me I need my fuel injector cleaned, is that true? Someone else told me I should re-tube my engine, like getting a set off all different tube sizes at my local suto parts store and re-tubing it all. Any help? suggestions? thanks.
