Well the car is idling quite unstable, its funny because when I switch my dim lights on the idling is much smoother as it sits at about 800rpm, sometimes I feel like just driving all day with the lights on. Well I wanted to service everything together to make it run more efficiently since I will be doing a lot of driving on the motorways etc. To be honest I had a Micra 1.0 which as a official record would do 46mpg, the corolla 1.4 figure is 42mpg but it feels more like I am doing 30mpg with the corolla, trust me you can not drive slower then me, I am a driving instructor in the day and so I never go over 30mph in the city and always try to get to the high gears. Anyhow at this rate I will end up selling this car, I don't think its as good as my old E11.
