I inherited my late brother's 2003 5.4L F-150 and doing some clean up on it. I replaced the PCV and the hose. I thought I had it all hooked up correctly but the truck seems to be misfiring. Can anyone point on the touch points for the two long hoses that come off the PCV itself? I have the main PCV in the valve cover and 90* to the back of the intake... The other two long ones are connected to the two nipples off the throttle body. One has about a 90* bend and the other doesn't but the hose seemed to fall exactly in place, however before I removed the old hoses, nothing was connected there before. Any help would be appreciated.
I stole this pic for reference, but it seems like there may be some variant of the TB
