How is it possible ?

Thank you 19963. You saved me some money. I was about to buy a trickle charger.

You will need a charger that has a transformer in it to charge a totally flat battery.

You can trick a electronic charger into doing it. It requires you to parallel a good battery with the dead one. Then when it starts charging remove the good battery.

Inconsistent voltage can most definitely cause stalling and other sensor and ignition issues. I'm pretty sure once you get your battery charged up or replaced you'll be good to go.

12.1V is not a fully charged battery. Any reading under 12.4 means the battery has discharged.

Another thing you can do with a dead battery is to hook it up in parallel to a known good battery with jumper cables. Let it sit for a couple hours to "equalize". Then you should be able to hook up the modern electronic chargers.

I actually did this at work with a fork truck battery that was totally dead. Our "smart" charger wouldn't charge it, the "bad battery" light would just come on. After I hooked it up with a jumper cables to another good battery we had laying around, our smart charger was able to start charging it.

That battery still works fine 6 months later. Having said that, if the battery is damaged, no amount of sorcery will bring it back.

Hopefully between cleaning the IAC and getting out and driving it to relearn some adaptive parameters you’ll be good to go.

Do you have a scanner that reads live data?

I’ve been successful cleaning the IAC in place by removing the vacuum hose underneath and shooting cleaner up into the IAC until no more black chunks come out. Then hole the throttle wide open and wipe out what you can reach with a rag soaked in cleaner.
