Also after I fixed a major vacuum at the PTC on the air intake hose it started making this noise that sounds kind of like a deep low boing sound. Not making it now, but thought that could possibly be something indicating an issue. For those who may have played legend of Zelda ocarina of time the noi...

A little update: redid PCV(lines and oil catch). Haven't done banjo bolts. Currently the codes are now evap, vvt, and cam position. Oil pressure sensor is leaking, and I'm suspecting that's the vvt code source. Thinking purge valve is my vacuum leak, and may indirectly be creating the poor condition...

Just wanted to share my diy on my PTC sensor! Looks like shit, but should be well sealed. Waiting for sealer to cure and I'll give an update. (Part of the attempts at fixing surging idle, did PCV aside from banjos that are on their way to find out that the PTC is really a POS)

I think it's the same as the one you're mentioning, and my ptc doesn't appear to have an outlet where that little elbow would go in the diagram (but has a spot where it looks ...

It's in decent shape I think, aside from some engine issue and common front end stuff. 179xxx mi Engine prob...
