Starting issues
I have a 2000 C230 K and it's been occasionally doing this weird thing when starting the car. As it's starting, it will start, but the rpms will drop and the car seems like it is going to stall. However, it never does stall. It will start up and run fine. This only seems to happen when the car is cold in the morning.
Today, I had one point where it didn't start on the first try. It did start fine on the second try though. I'm just pretty concerned because this car has always run fine except for some occasional problems. It has never left me stranded or anything though.
So what could be causing this problem? By the way, I pushed the car today a little bit and allowed it to come somewhat close to red-line. It has no issues at high rpms, except for the usual loudness. So I don't think my current issue is fuel pump related. Also, I reset the ECU recently and the engine air filter was just changed out a week ago.
Thanks!
Anyway, here are some pictures. I cut open the old filter with a hacksaw and saw how dirty it really was.
