Melted Catalytic Converter

I'm on my last-ditch effort with my 2009 Chevy Malibu 1LT with 191K miles. The car runs decently for its age and mileage. A few weeks ago, I got an engine light and a P0420 code. The muffler shop got the same code and said I needed a new Cat. $1100 and 2 weeks later, the engine light and code came back. The shop told me the first one they installed was melted, but they warranted it and replaced it. Has anyone ever experienced this or could point me in the right direction? I can't leave it at a shop for diagnosis, as it's my only transportation and I work in construction. Can I just replace the spark plugs, injectors, and coil packs, or is this maybe a timing issue? Please help..

09 cheyv malibu 190k mi P0420 code

Over the weekend while driving on the highway my engine light came on. Code came Back as P0420 bank 1. I had a minor exhaust repair in June, front exhaust pipe broke off flex pipe if i remember.

7th Gen fuel economy

I recently saw someone asking about fuel economy on the 7th gen malibu and I just wanted to sort of follow up on their post. This was today on my 09 1LT with 190K miles. Cruising flat highway for a good 10-15 miles before coming to a slight uphill, and it was still going up before the hill. I'm honestly impressed with my normal fuel economy for a 17 year old car. I typically average 33-34 on my normal route, but today was even better on a mostly flat route. Nothing was modified outside of a K&N air filter and spark plugs, and injectors were replaced in 2023.

STICK DRIFT HELP

To start, I don't really think it's a stick drift issue. More of a broken/unresponsive part. I have little to no response on my left controller's analog stick when pushing it in roughly the 1-3 o'clock position. Like if I push the analog to the 1-3 position, it will just stop and return to center. I've removed the faceplate and analog cap, cleaned with alcohol and an air duster, and it seems to help for an hour or so, then back to being unresponsive. I know there are kits/replacement analog sticks to swap in, but I don't feel qualified to do that. A replacement controller is like $80 from Meta. Are there any other cheap fixes before I end up having to replace the controller completely?

Budget stock replacement speaker

One of my A pillar tweeters and rear deck speakers has started to crackle a bit. What are some good budget coax 6.5, 6.x9in speakers I can install with the stock head unit in my 2009 Malibu?

Help with dash cam and carplay screen hardwire

Id like to hardwire a dash cam, and Carplay screen in my 2009 Malibu. Id like to power the Carplay screen with ACC power and the dash cam with both BAT and ACC for parking monitoring and battery V cutoff. Can both ACC wires be on one fuse? The easiest means to me is to add a female 12v cigarette fuse tap with the dashcam connected to a ACC fuse, and the dashcam BAT fuse tap? Is this the recommended method or is there a easier way?

Future idea for Exfilzone

With Exfilzone being one of, if not the top, VR multiplayer shooter/extraction games currently out, I wonder what people's thoughts are on the future of the game. I would like to see the game go on a much larger scale, more of a mil-sim, maybe like an Arma VR route. Maybe armored vehicles and transport helicopters to start. Having games such as ForeFront and Warplanes its possible to develop attack aerial vehicles.
