Finding air leaks and replacing throttle body gaskets on a Renault Logan K4M
The Renault Logan 1.6L K4M engine's RPM started fluctuating when cold.
Fuel consumption on the highway also increased by almost a liter. 7 liters per 100 km, while it used to show 6-6-3 liters per 100 km. We're using a smoke generator to find an air leak. We also cleaned the throttle body of dirt, which is now approaching 90,000 km.
