Mercedes c 180 start up problem
My c180 have a very rough and irregular cold start.
The engine is misfiring, idle irregular, jerking,
almost shuts down then fires back up. This lasts
for about 30 - 40 seconds then engine smooths
out and runs normal. It feels/sounds like a
switch/valve/sensor that kicks in after 30-40
seconds where after it runs normal. This only
happens once a day, usually in the morning or
after about 8 hours since last start.
Can someone please help?
