Actually I just had my 02 Westminster project suffer from an odd issue. I would run it maybe 20-45min at idle, drive around a bit and when I put it into P the engine would nearly die 100%. It did this several times and one time it popped up with a pending code of P0441. I had two Bosch LR's at my local salvage yard and I got the entire Purge Control Valve for like 8.00 plus tax. I slapped it in & it hasn't done it since. Most of the time it never threw a code until that one time and I had my scangauge II connected and caught it before a key cycle. Up until that freaky business I've never had a Purge Control Valve on a Bosch V8 ever do that.

I've heard plenty click loud (Bosch Unit's), and still work fine, and then I've had them just up and die. I normally always use the Hyundai Replacement vs Bosch, but this time I was able to grab one locally for cheap.
