Mercedes 190 e

I have a Mercedes 190 e to the one that I put together, it is torn and everything is raised well and the engine throws well but the release varies a lot, and looked at the empty tubes to see if they were well connected, sensors, cables, ignition and more and of more thinking and fallen that to see if it sucks me air by some place, what do you think?

thanks a lot

Check the empty tube that goes to the progress module, behind the left lighthouse, and that the water temperature sensor is connected.

Hello friend, apart from what the partner says, check the speed sensor, tell us how you are doing, greetings.

Companions and looked at everything you have come to me and nothing, I know some discoveries, I don't know if they are good or bad, hahaha.
I explain to see if someone can lend me a hand. First when I connect the tube that goes from the air filter housing and the vent of the rocker lid to the boot switch the resenti low shakes but if I remove the air intake that it carries in the collector in the rear (it is a finite tube) the car rises of turns and seems that the release improves it.
On the other hand of the starting valve, an air tube is also to the rear of the cylinder head and enters as an air regulator (which is full of oil mixed with water, from before fixing the cylinder head) the output of this regulator goes to the base of the plate of the injection and when disconnecting it also rises the release, I believe that the problem is in that air regulator but you no longer know?
Then also speaking of the electric part if I unplug the regular of Relay the car does not varied.

Thanks for your help

Good night Bombi05. What do you mean when you say the tube enters as an air regulator? If it is the IAC and is full of why, it is sure that it does not make its mission, you have to leave it clean. I leave you this image so you can see if that is.
