Hello,
If you suspect there is too much vibration, you may want to check the engine mounts. Sometimes this can be done by putting the vehicle in drive while the left foot is on the brake and using the right foot to quickly throttle the engine, you may hear a knocking or feel a big vibration if the mounts are worn out.
About a fuel injection service, it does depend on the type of service. If you are referring to a fuel system cleaning of the valves, the typical mileage interval the general shops give is around every 20,000 miles for modern engines. The parts stores also sell a fuel injection cleaner to put in the gas tank that is also beneficial and is also usually given during a service.
Hope this helps,
William
