The Noico stuff on Amazon is great. I think I used about 100 ft2
Just checked, and apparently it's unavailable right now.

I do remodeling etc, it wasn't my deck Bob.
The entire frame of the deck was rotted, not just the decking itself.
Looks like they did a nice job on yours.
My favorite combo for the plastic railings is white posts, white rails, and black spindles.
You can try removing and cleaning it, you can try using a restrictor plate, you can try a new IAC. For me, it always comes back eventually. Pretty sure I've seen some use a GM(?) IAC also.
I believe it can be fixed in a tune however. I just need to get back there for a tune one of these days/years.
There is a YT video where someone did it. He had to cut back some of the foam etc from the back of the rear seat (both the back and bottom). He also had to charge brackets if I remember correctly.
I just tore down a deck last week. Was built with PT wood 17 years ago. We were originally just going to replace the painted decking with vinyl, but the joists were all rotted, most of the posts as well.
For me, I liked the stealth of it. Underhood if you're not paying much attention, it just looks like I have a CAI in the fender.
The turbo can be seen through the front drivers side wheel well.
I can post pics later if anyone is curious.
