Alright, I fixed the valvecover leak and replaced all the hoses in the car, as well as ****in around with the ICV. The car runs now, though it was not starting for a bit - found out that some of the fuel injectors werent connected, hit the contacts to the injectors hard - they clicked in, and I was starting... now after that the RPM meter was through the roof - literally it was going past 8 and the 9k RPM... yet the car was acting like a normal idle, i reconnected a bunch of sensors and it is fine now. The problem is - when it idles and goes lower than 1k RPM in general it is very very rough... like really rough.. the car is shaking - i dont think it ever was like that and I can hear the engine when driving - couldnt hear it previously. I do have an exhaust leak but i am saying - more so than that leak. Does anyone have any idea what it is??

-Thank you, Artem
