My '01 gifted me an engine code (believe it was P0136) and I determined the cause was either the (1) O2 sensor behind the RH/passenger cat or (2) the PVC hose that routes from the RH valve cover to the back of the intake.

The hose was $32 and the O2 sensor $30 or so on Amazon. I picked up the hose from my local Ford dealer as I forgot to add the hose to my cart before checking out :Violin:

So far after replacing the PVC hose/line, no more check engine light. I have not yet replaced the O2 sensor, as the leaking hose may have been causing the code.

My question for you guys is this: What do you recommend about sourcing all the various vacuum/emissions hoses that plumb around the throttle body and upper intake? Mine are in pretty rough shape, with some of those hoses molded with specific bends/twists/ends. Has anyone done this? Or do you just piece together with whatever is lying around? Don't think I'll get another 120k out of these rubber hoses. Thanks!

Totally agree with the above ideas. I went to autozone and schucks and bought hose by the foot and replaced everything that connects to the throttle body on my 1998. I also had to do the same on my 2004. Cost is pretty low doing it by the foot.

Same here. A few different hose sizes, a couple hose T's and L's to keep everything clean and free from kinking up as well.
