The clio was running strange recently cutting out at junctions, not idling right and on the open road not driving very smoothly. Also sometimes it failed to start which was caused by oil coming out from the air filter housing and dripping onto the crankshaft position sensor. I did this to remove the throttle body and clean it out, also the crankshaft breather pipe is located in here. In the video i didnt actually clean these parts as i did that last week but they were covered in oil and crap, the crankshaft breather had a lot of old sludge which i had to scrape out but its very clean now. The throttle body took a bit of time with some carb cleaner but as you see in the video thats how clean it needs to be. It has made a huge difference to the car, there is no more lights on the dash, it has been running very smoothly and on the open road there is no cutting out or spluttering when planting the throttle.
