Initially I like the vacuum line answer. However, you said you have to get the car running because of lack of truck.
Has the car been sitting without running for a while? If so, did it sit through the winter with heat and cool variations causing some internal condensation?
Did it sit a long time with no fuel stabilizer? Was the tank full or close to empty? Condensation inside the tank could clog a fuel filter. Replacing the filter with water still in the tank would clog a new one.
Any of the auto parts stores will let you use a code reader if you do not have one.
Still thinking.

Just going off of memory, the first is a misfire in #2 and the second is lean on that side. Replacing that injector is a good start Run some good injector cleaner after that (3M, Techron, Redline, gumout regane)
Going off of memory? That's awesome. I did look up the codes and agree with their meaning.
I am curious why you would recommend changing the injector then run a cleaner. No disrespect but that seems backwards to me.
Not a rocket scientist......

Changing the injector to another cylinder is a good idea but if I'm going to take the time to pull the intake I'm going to replace the it with a new one.

Yes the sat under a tree for over a year and the tank was almost full

I've let gas sit in a boat tank for several months and when poured out it was pea green
U may have to empty that tank out
Ethanol gas is a joke. It has to be used consistently. It can not sit

Get rid of all the old gas. Put in high octane with Sea Foam.
If it does not work look for the vacuum leak. Sitting for a year is tough on rubber parts. It runs better at high RPMs. High RPMs creates an abundance of vacuum, possibly masking a small leak.

I think someone like Meaujeaux2 can probably give you some pretty straight up info on what typically causes this.

Only thing left is injector or bent valve.

I forgot about the pcv leak that we taped.

Do you remember the third code?
Did you also consider a little Marvel Magic mystery oil in the gas and oil? Anything sticking may be helped by this. I am trying to think of the cheap and easy things to try first. (No Lindsay Lohan pun here)

I'll have to try and find it tomorrow. It's gotta be in the car somewhere. I can go by autozone and get a copy.

Could be something as simple as a vacuum leak or some as fricked up as a leak or crack in your exhaust manifold
I know this because I too had a 2001 mustang
In 2004!!

Didn't realize the question had already been answered

Because if it is already bad enough, it needs to be swapped. Other ones are still good to where they don't misfire hard/frequent enough to throw a code
I remember random stuff, and trouble codes are one of them

It actually does have an exhaust leak but it's on number 6 cylinder which is on the opposite side as 2

I would suggest that you deal with the fuel first, it most likely has ethonol and has absorbed enough moisture through the vent to cause issues.
Moisture and fuel injecters do not mix well, if they are not shot they soon will be.

It would cost about 240 dollars to replace them all. I was hoping that I could just change the bad one on 2
The 240 is just the injectors that would be me installing them

I was refering to the fuel itself. Drain the tank and burn it in something with a carb. if you like.
Once the gas enters phase seperation the alcohol becomes a water magnet. Get it out and burn it in something with a carb. if you like.
Water is an instant death for fuel injectors.

if its not you O2 sensor then its your fuel injectors
