When the light comes on without flashing, it just means an emissions problem, when it starts to flash it has become more serious. I suspect that there was an error putting the plugs and or wires. That computer can determine if there is a misfire and it will put out a P040X, code where X represents which cylinder is the problem. This will help you not have to take each one apart. If there are more than one, check each number.
Ex. P0401 means there is misfire on cylinder number 1
P0400 is a random misfire detected.
If you take it to an Advance or Autozone they will usually scan if for free.
By the way, if you used cheap plugs instead of platinum plugs that could do it too.
Hope this helps.

SOURCE: My cars Idle RPM often
a better question is why is idle so high? could be a vaccum leak or other issue. Adjusting the idle circuit is not the answer. Since the check engine light did come on perhaps you can retrieve a trouble code...maybe even a bad tps
