You need to pull the codes from the OBD diagnostic socket to see why the check engine light is going on. Use the info here in the 700/900 FAQ feature area to do this and to help interpret the code(s).

Other things that come to mind: Excess condensation in exhaust system or new exhaust system with joint leaks? Cat converter starting to break up? -shake cat up and down and listen for loose pieces. Maybe something as simple as clearing the codes and giving it a real good highway drive will set it right.
