Idle real low til it eventually dies
Hey guys. I just got my 2003 350z VQ35DE a couple months ago. I had an error code to replace my knock sensor, and I did so. In replacing this, I removed the throttle body, intake manifold, and the fuel injectors. While putting it back together, I watched the youtube video on how to teach your car to idle correctly, I have done this about 5 times now and the more I rev my car, the more it wants to die. Also when it gets to around 200rpm, the car starts shaking really badly and theres a knocking/tapping sound coming from the engine. Now I'm not a huge tech person but and getting into it with this car, so I'm still not sure if it's just the plenum shaking and hitting another metal part? I just don't know where to go from here as I don't want to **** up the car even worse. I've looked up and it says I may need to clean the TB... or replace it.. and if the engine IS actually knocking... then what do I do from there? Anyways hopefully somebody can help cause I am completely shot in the dark lol

Did you unplug the coils? Make sure the connectors are on the correct coils. People often swap the back two on the driver's side. Easy to do.

I don’t believe I had to touch the coils at all. I removed the pleneum and then the fuel injectors were underneath, which I also removed. And thats everything that had to be taken off
