I wanted to help out people that encounter this problem in the future.
The pic is what the problem looks like.
So, my truck would have a jerkish idle to it and the check light came on. I took it to get an oil change since I needed one and just asked if they could check and see what that loud blowing or (sucking noise I later found out) was.
Ok so it was a hose easy fix, nope well yes but finding the part was the tough part. After going to oreillys, autozone, napa, advanced auto and being told it was an upper radiator hose I decided to hit the forums.
Found it! Itís a PCV elbow. I went back to the autopart stores and they suggested the usual pcv elbow. Nope that wont do it, it is not a generic elbow. This thing is complicated it has three different sizes on the hose itself, (LAME). Ok so nobody has it, back to the forums. After searching and going through the forums everybody says go to the auto store. That is not going to do it for this odd shaped hose. I then got to hoses to match the top and a plastic connector to fit the PCV valve. Truck still ran like crap. Went to
This is the part to fix it.
