So I would like to bounce off you fellow 6th gens how bad I probably messed mine up....

So I to prepare my car for a road trip, I did the sea foam to the intake manifold, oil and gas tank, performed an oil change and I also sprayed throttle body cleaner. An issue with the throttle body cleaner was that the butterfly valve wouldn't open when stepping on the gas. I used the plastic end of a screwdriver to hold it open while spraying.

4 days into the trip, the CEL came on. The code was about high revolution. After clearing it, it was all good.

That was 2 weeks ago. Today, the temperature read -22 and the CEL came back. I turned off the car and waited 15 minutes. When I turn the car back on, it says i have an empty tank with the low fuel light on, the CEL on and the AC on @ 75 degrees half-full blast. This code, P0463 (pd) read : fuel tank level. sensor circuit high input. Also, when I take the key out, the AC lights are still on.

I drove 10 minutes to my house where I put the stock airbox back on and disconnected the battery for 20 minutes. Car drove fine with no problems for 5 minutes until the door ajar icon was blinking but the info screen did not detect it. It went away on its own after another 5 minutes. Now everything seems back to normal. WTF?
Any help is greatly appreciated.
