Hi everyone! I just recently got a 2005 1.4 SXI Astra. I was driving home today and I was accelerating and when the RPM hit around 6k I got a flashing EML light and the car was very sluggish. It was in limp home mode. Got home, plugged in the opcom and i had a random misfire code and a cylinder 1 misfire code. Any idea what would cause this?
