Hi,
The gap wouldn't have changed. If you have the coils back together correctly, I would be looking for an engine vacuum leak. You may have by accident disconnected one and that will cause a rough idle.
Here is a link that explains how to locate and repair a vacuum leak:

Also, if the check engine light is staying on while the engine is running, have the computer scanned to determine why it's on. You may have gotten a faulty coil and it will let us know which cylinder to check.
Let me know what you find or if you have other questions.
Take care,
joe
