Start with the fail safe modes. This is usually a voltage problem within the system. I would connect a multimeter to the battery voltage where you can see it while driving. If it is around 12V or lower when driving instead of 14.5V, the system will throw the fail safe modes. If you do have a low voltage issue, check your power steering reservoir and make sure it is not leaking from the hoses beneath it, they will leak directly on the alternator on the 3.0L and cause problems with charging.
Next, replace that broken MAF sensor and replace any obvious broken vacuum hoses, then clear all those codes and see what comes back. Take each problem and solve them one at a time, as others have mentioned, we have a plethora of knowledge here and can help.

Exactly my thoughts!
So many things are wrong, I will try to go at them one by one.
I did lots of testing today.
After coming home from work connected the car to INPA and played around for a bit. Obviously the battery drained a bit with the key in the run position.
I found.it weird that I could only scan the engine and transmission.
Engine:
Transmission:
Somehow all the other modules were inaccessible:
After scanning everything, I moved on to the voltage. INPA was showing the voltage around 11.7 and the instrument cluster 11.6.
I checked with the multimeter and it showed 11.8
I think I trust the multimeter the most.
I remember when I fully charged the battery 2 days ago, it showed 12.9v charged, and 13.9 with car running.
11.8 is kinda low, but if I turn the key off from "on" position, the voltage will go up.
So next I mounted my multimeter to the rear seat and connected the probes to the battery.
Whe I was driving the car, the voltage would be around 13.9 volts. With everything on (heat, high beams, radio, wipers, low beams etc.) the voltage was about 13.8v the whole time. The car glitched as always, but the voltage didn't jump around like on vehicles with a bad alternator.
After I drove around for half an hour (city+highway), I came and and parked the car. While running, the voltage was 14v. When I turned it off, voltage was 12.68
So it doesn't look like I have an issue with either the battery or the alternator, does it?
