Sorry I have a mistake on my drawing. There should be one more main pipe that goes directly to EGR valve, and those two fork pipes should be connected to DPMF sensor (I saw it on diagram on Google). One of the sensor hoses was unplugged and I plugged it on the pipe but nothing got better or worse. Then I tried my last option, unplugged the vacuum hose from EGR and blocked it to prevent vacuum leak. After that driving got too much better and very smooth, but idle got worst. When stay in place it is still high, about 1250, but when drive in idle, it fluctuates between 1000 and 2000 (I made a short video). When driving in some shift, and want to stay and change in lower shift, in that moment while stopping and pressing foot brake and clutch, rpm rises to almost 3000 until you put the gear in shift and rpm normalizes while unpressing the clutch slowly to get drive. Also what is suspicious (maybe not a factor) is that digital speed meter show some value when staying in place for example 20-30.
