Hello, sorry if this is in the wrong thread that I'm posting this but something happened to today when I went to start my car. I live in Ontario and naturally it gets cold in the winter and right now it's -18 celcius. I started my car this morning it was fine warmed up and worked and then parked it. I went to start it about 8 hours later and the engine stayed reving at 3000rpm for about 5 min then dropped down to about 800 and bounced from there to 2000 during this entire time I was unable to use the gas pedal as it did not respond at all. Can anyone help.
