Engine light is on and will only go ten mph

Looks like your vehicle went into limp home mode. You would need to have the vehicle scanned for codes and post them on here to get an idea as to what is going on. If you have a code reader then here is a link on how you can do it yourself.

Also when you post the codes let us know what engine size you have, is it the 2.0L or 2.3L thanks.
