Engine Management Light on?

Got a 2002 Toyota Avensis 1.8 VVti, 121000 on clock, changed plugs today and engine light on now?. Checked air filter was fine so left it. Any ideas?. Only done a short journey since & ran fine. Thanks

done
If the light wasn't on before you changed the plugs, are you sure you've used the correct ones? What else did you touch?

The first thing to do is to get it onto a code reader,there are hundreds of fault codes out there which can bring your light on,no point guessing.
