Update! Stumbling/bucking during revs/acceleration.
Update: One of the plugs was broken and it was arcing to the coil.
All the plugs cane out smooth, surprisingly, replaced them and the coil. Good as new. End update.
Today I went for a drive and noticed a slightly erratic idle. I gave it some revs and noticed a stumble, almost like a stuttering.
While driving in all gears under mild to full acceleration, it stumbles bad to the point of bucking..
Could it be bad gas? It's not the tune as I had to return to stock for emissions reasons..

Might be a stupid suggestion...but are you still running the stock tune? Do you have an aftermarket CAI? Kind of goes with what kput said but could be as simple as that I suppose. Good luck with the cleaning and let us know how it goes.

I was about to mention that but figured he put the stock air box back on with the stock tune.... But then again maybe not? Lol!

I put the stock intake and tune back. Threw in a cleaned and oiled drop in filter for the time being.

I have read that sometimes people put to much oil on their filters which in return ***** up the MAF readings. Try cleaning your TB and MAF tomorrow cause theres a good chance it might be that unless you honestly didnt overload on the air filter oil.
I remember a few days after I got my car I installed my hid headlights and forgot to plug the MAF back in and was getting the same symptoms as you. I **** myself thinking I messed up my new car somehow but a few minutes later I realized I never plugged it back in. Moral of the story -- Its the little things that you should check first

Seems to have dissapeared the next morning. Last night I threw some 93 in a tank that had half a tank of 87 and drove it for a half hour. Maybe it was bad gas.
This morning I cleaned the TB and MAF. Seems to have dissapeared.
