So i was performing some minor troubleshooting on my 2010 wrx and i disconnected and reconnected the battery. Afterwards, i noticed that the response on the gas pedal is much slower, and i have to push it down further for it to do anything at all.
I haven't pushed the car too hard since then, but it does not feel to have lost any performance, just the weird pedal thing. I have driven it about 10 times since, then about 150 miles, and the issue persists. I do recall it feeling like this when i first got the car, however i didn't know any better because this was my first manual car so i figured i was just being dumb. Unfortunately due to that i don't remember how long it took to go away, my assumption is that the ECU is "learning" or something, who knows.
So two questions, 1) does anyone know why this happens, and 2) how long it takes to go away?
