Sorry Baum, didn't even see your response. I am almost certain it's a battery issue. When I start the car after sitting for a period of time, airbag light is on. If I turn the car off, and start it again within a few hours or same day, no airbag light. Ford seems to always have issues with those yellow connectors though. The Explorers suffer from the same problem. Thanks for the tip though!

So today I went to S.O.S. to get plates. Got my first personalized plate, figured why not since I have one of my dream cars. Got the temporary window tag, stopped at Muffler Man since it was right there to ask how much for what I wanted, he just got busted for a catalytic converter so he will not just put a muffler in place of that third cat like I wanted, but oh well. We decided for now, install that third cat.
I came home, let the LS run for a bit to warm up, and was still debating on driving it to the shop or having it towed. Towing is $50 flat rate, ticket for no exhaust is probably a bit higher. I was going to drive it to the gas station regardless, so I could finally get gas, and then found out that it's actually not stupid loud when I'm cruising, only on acceleration.
Threw $35 bucks in gas in (time crunch, pump was going so slow), and headed to Muffler Man. I had a BLAST driving the thing. I never really accelerated hard, but god the thing is a dream to drive. As far as I can tell, there are no other issues. I do however want to replace the upper ball joints, as I saw the boots were cracked when I was replacing the fuel filter. I'll also probably throw on new pads and rotors. Battery this Friday for sure, and now that it's road ready, I can do some cosmetic upgrades. Tint will be done hopefully Friday or Saturday. I feel so naked in the car with every window clear as day.
I'd like to thank you guys all for your help so far, definitely would've been so much more work if not for you guys!
