If it's leaking injectors wouldn't it start rough from the start? Also wouldn't it be a consistent cylinder misfiring? But it's random, like today it was only cyl 6. I doubt all my injectors are leaking or I would definitely smell heavy gas which I don't. And I don't think it's technically "misfiring" more like it's slightly retarded because I I rev up slowly to like 1k rpm it doesn't misfire.

And sometimes it does start rough right away sometimes it does the normal high idle (perfectly) and as the rpm settles down (lift being adjusted by valvrtronics) the roughness begins. Again intermittently and random.

Also for me shutting the car off when idling rough and restating doesn't fix it at all and so far this is always been the case. Restarting never does anything. Just have to let it go away on it's own. Have even restarted it 3 times and no chance.
