Just had something incredibly strange happen. Got in the car, started it up and it idled at 1200 as normal but it was smooth! My brother even noticed it. Seemed to run for a bit longer than usual (at a guess 60 seconds). This seems like how the car should be operating. The only parameters that I can think of as being slightly different are that the car has sat for 48 hours and the fuel level is very low (in the red dashes). Also its very cold in Melbourne at the moment but the car gets garaged so thats probably not related. Was going to make some logs but was in a rush so decided not to.
