Getting Car into glory Again (S70 GLT, 00's)

[S70GUY]

If anyone here remembers me, I'm the guy from the S70 GLT, the car managed to start but I couldn't find the cause, I come here for more help from you experts. This time I have some new problems and codes, if you can tell me what to do to investigate properly it would be helpful, the car will have a Stage Zero (Complete Tune-up) After I have more money (Disadvantages of Living in Mexico) The car has 2 lights on the Dashboard (Brake & ABS), previously it had the transmission Safe Mode, now I can activate/deactivate it but the car still doesn't seem to increase revs (it doesn't rev to more than 4K) although there are no transmission codes but it does follow. Another problem I have is that I have to press the accelerator several times for the car to start any help is welcome and an apology for the long text
