My pcv hose was kinking for god knows what reason, it was 3/8in 275psi braided pic hose, I have a catch can inline and needed better line. I replaced it with 3/8 315psi multi purpose hose. Brand new pcv grommet and valve, all works great. I start it up and when it got to normal idle I noticed it sounded super rumbley, constant 750rpm idle but it sound cammed. By letting it idle a few minutes it only stuttered a few times rpm might have fluctuated a little but it just sounded like how a drag car idles it's not always constant. It doesn't seem normal for this car though, stock internals, intake and exhaust done, some cooling mods, that's about it. My other f23 doesn't sound like this. I can get a video up, you will be able to hear it because of my muffler will rattle. I need to know if this is normal, not urgent I am going on vacation tonight. I am thinking if it is a problem it's fuel, vacuum, or valves. I just had my valves adjusted 2500mi ago.
Edit: it no longer stutters and pops, at one point it did it a lot until I put it in gear and I never heard it again. It still sounds rumbley at idle though. I don't think it's misfiring, I suspected it earlier but not anymore.
