Kompressor cold starts

[benzonline]

On my 99C230K I noticed its giving me in the mornings, 4-5 "shakes" when it fires and starts to run and is then smooth....I then noticed when It started to do that, that there is no more raspy, gurgling noise you are supposed to get with this engine when cold which im told is the kompressor turning on when cold to warm up and when it does occasionally I dont get that shaking hesitation. Now, the kompressor does work because it engages at 2000rpm (sounds like a AC compressor).

Could this be the air flap actuator by the air filter making it not come on when cold or a bad solder joint in the K40 unit I heard about before?


Thanks so much need help!!

You need to change your spark plugs. Thats what happens when a spark plug on one of the pistons misfires if it ain't the spark plugs it may be the wire harness to the plugs but I am 99% sure its the spark plugs!

I just bought this car used with all records and 80 000kms.

Shows that the spark plugs were done 1 yr ago and less than 10 000kms ago....are u sure? Becuase it one plug was not firing well it would do it while driving not for a few seconds?

Aswell its the kompressor not turning while cold at lower rpm which is causing it to choke for a few seconds.
