[W203] C180K - Unstable engine speed in the morning
Since a few days, it was a little cold in the morning in Tunisia (+/- 6 °C) and since my C180 Kompressor of 2005 with 204 000 km in the meter gives two (02) blows with each starting in the morning.
The fault only appears during the first start, even if the vehicle remains stationary for more than 12 hours, The fault no longer appears. (See the video below)
What I've changed so far:
1- Spark plugs
2- The temperature sensor of the coolant
3- The thermostat (sometimes messing)
4- Battery (830A and 100Ah)
The fault worries me !!
I hope to find help from you and thank you in advance.
