There was white smoke coming out of the exhaust and distinct smell of gas. Super rough idle so I popped the hood and engine was shaking pretty bad so I shut it off.
I had tried leaving the car off for like 30 minutes and hoping something would reset, but no luck. Had to drive home about 4-5 miles going about 30 the whole way and trying really hard to avoid using the accelerator.
Had it towed to an indy shop (out of warranty :/ ) and they said all 6 cylinders are misfiring, 1 of the coilpacks is completely black, and he thinks the HPFP is shot - he's still researching - but I guess makes sense why the car was bucking so much under any amount of acceleration.
Anyone else had a similar issue? I've been checking all the F series N55 forums and can't find much that is similar.

Cracked charge pipe perhaps?
