I put way to much oil in my 2006 Mazda 3 (2.3L) engine by accident and didn't realize it. I fixed the issue I think. what should I do now?

Depending how much you overfilled it, Tom may be correct, gaskets and seals might be or become an issue. If just a little, I wouldn't worry. You did catch the mistake and corrected it quickly, which is very good. There may be excess oil built up in the PCV or EGR system that should clear itself out on it's own.

awesome! thank you for your help. I took it to a mechanic my friend uses and he looked it over and said everything checks out. and was nice enough not to charge me for the look. the rough idle smoothed out and everything seems to be functioning back to normal. Thank you!
