I have an issue , when the car is cold , is continues idle the engine until the car is warm . When is warm is not issue at all . Also looks like is missing something in the front of the engine ,here a picture can help . Thanks
Yes, you are missing the front engine cover. See my car below:
Also, what exactly is your idle problem? usually, when car is cold, it idles at around 1000 or above until the catalytic converters warm up. What exactly is your question?
I have the engine cover . But looks like someone remove the secondary air pump goes in the front and also 2 purges valve . If you can remove you cover you will see it . Car idle a lot , and even sometimes turn off . And the rpm keep moving between 600/1200 alone , so I need to rev the car to get it warm . Once the temperature is close to 90*. Car sound correct no issues at all . I hope you understand what I mean .
Some AMG's had the secondary pump in some states by law other cars didn't have the pump.
Did you buy your car like that?
yes I bought it like that , but my car when is cold is idle a lot and rpm is moving , until the car get warm , this is why i was thinking the problem is there . Any idea ?
Does RPM needle go up or drop several hundred PRM's on idle?
Perhaps you have a vacuum leak in the system?
Have you checked if rubber hoses around intake manifold gone dry rot, they will eventually leak air.
Same goes with rubber O-rings when they go brittle.

i need to check them . Yes the rpm drops hundreds and even sometimes ,The car shutdown. The thing is when the car is warm drive amazing no issues at all . This why Im not thinking on a vacuum leaking
i try to read the codes , cause is 38pin , with icarsoft adapter and 3 different diagnosis machine . But doenst want to connect to this car
If no-one else can help you, then you should visit local dealer or a specialist shop, hook your car to STAR, it will cost you but then you will know what could be the culprit?
The 38 pin fitted to older cars is not very smooth to work with compared to the new system OBD port which came in the year 2000.
