Answer
Ricky,
To reset the check engine light, just remove your negative battery cable from your battery for a couple minutes.  When you reattach the battery cable and start your car, the check engine light should be off.  If that does not turn off the check engine light, then your car's computer is still detecting a problem.  If you have an AutoZone in your area, they will hook up a diagnostic tool to find out why your check engine light remains on.  They provide this as a free service.

A rattling noise when turning can indicate a bad CV-joint, broken tie-rod, or a broken ball joint.  Have your mechanic inspect your suspension parts.  If you don't get that fixed, it can throw off your wheels alignment and ruin your tires over time.
Good luck!
