As I've been tuning up my newly acquired '99 GTP and trying to chase down a formerly-sporadic 0171 code, I got to changing my PCV valve. After doing so the code has gone from sporadic to constant and I can't help but wonder if I was supposed to replace an o-ring and failed to do so?
And I'm noticing that one of the GTP guides on Paul's site does specifically reference replacing "the spring and any o-rings or rubber gaskets" but I don't recall seeing any when I removed the valve I replaced.
