You may possibly have a boot that is not seated on the spark plug correctly or a plug wire is damaged from pulling them off the old plugs. If you have a multi-meter you can test them for continuity.
You should, before you do anything else, get the trouble codes pulled to see what error code is making the Check light come on.
Any Advance Auto or Auto Zone will do this for free.
