You're right, the lower grill looks terrible. I would get something close to stock. This link will hurt when you look at the price.

I would hook a scan tool up and see if you can find out if a cylinder is missing. It might be as simple as a plug, COP or an injector. I used Forescan to find my miss.
Forescan will also allow you to program your own keys. Very easy to do.
Lucky for me, it's the honeycomb one. Only $50 cheaper! 🤮
Looks like I'll be ugly for a while.
I've had Snap-On scanners hooked up to it and have been told, until it throws a check engine light, they can't see much. Crappy part is that it ran this way before all that work.
Only check engine light I have right now is for that stupid EGR sensor that I've already replaced once.
My curiosity is if it's running rough because it needs a tune.
