Unknown problem after some work i’ve done, please help

Now I am confused. You have been talking about the EGR valve in this thread. You said you took the EGR valve apart, but you had herd that it was calibrated at the factory. I responded that the EGR valve is not calibrated at the factory, so there is no problem taking it apart.

Are you now saying that you do not know the difference between the EGR valve and the throttle body? Take a picture of the part that you are taking apart and post it.

 

The egr valve was probably damaged to. begin with and you taking it apart did nothing.

 

When you put the EGR valve back together, it probably wasn't completely closed.

 

Did you replace broken bolt?

 

Old egrs get worn ramps. Cleaning it finished it.

 

Trying to think how "open" comes to be. Some pictures in this thread:

Yeah, slightly open is the natural result when you have spun the rotor all the way down against a spring, but have to let go at some point as you reassemble the stator over it, the rotor spins back a small way, and then you end up pushing the valve slightly open as you tighten the stator down with the screws.

If you have the valve off and in your hands at that point, you just push the pintle closed again with your thumbs. In fact, that's a good test that you have a good reassembly with nothing binding: you should be able to push it somewhat easily with your thumbs, but you will feel and hear that you're spinning the rotor inside by doing it.

More at this post (and even more at those linked from it).

Of course if the valve is attached to the cooler at that point, you've got no way to push the pintle with your thumbs.

Wouldn't expect it to matter much if the valve isn't fully closed when you put it back on, because the repair manual suggests the car is always sending pulses in the "toward closed" direction when it doesn't want the valve open, so even if you put it on slightly open, that should be fixed in a split second when you go to start the car.

But there have indeed been reports of rough starting/running right after putting a not-fully-closed valve back on.

Might make me think of using a scan tool's active test to explicitly send the valve to step zero before trying to start the car (if I hadn't already pushed it closed with my thumbs).
