I have a 2012 civic ex, it was -40 celcius today and the girlfriend started the car with the auto start let it run for about 20 min then it sat for another 30 or so she got tied up. When she drove home from her friend just up the street, it wouldn't go past 25 kmh and the check emission system error came on. When she got home and put it in park is started to rev on it own up and down up and down. I went out turned it off then re started it and the emission error, power steering error and check EMA error all came on, and it was still reving up and down when in park. It going in to the dealership tomorrow but anyone here of this before? I'm quite pissed off right now, seeing how the car only has under 1000 km and just over a month old.
