2008 Sport Trac wrench light on.

[Albright]

My wrench light comes on and goes off periodically. What could be the problem?

Many things could cause the wrench. Get a code reader (costs about $20) and scan for codes, even when the wrench light is off, codes should still be stored. Post the codes here or do a google search to narrow the problem down.

Thanks I will.

You can go an Auto Zone store or OReillys or whatever there is close to you and they might have a code reader. They can tell you what is wrong as well.
Good luck
