Hi,
As far as resetting the check engine light (CEL), it will be based on what type of code is stored. If it is a permanent code, it won't clear until the problem is resolved.
As far as the spark plugs are concerned, you shouldn't have any issues, but it never hurts to use penetrating fluid. When you remove them, take your time. If I have a concern, I turn the plug out two revolutions and then back in a half and continue to do that until it's out. By turning it back in a bit, if there is dirt built up on the threads, it helps move it, so it doesn't cause the plug to bind.

Let me know if you have other questions or if I can help in any way.
Take care,
joe
