great article. I thought this was my issue, but my mech says now way in hell.
I copied it to a work document to be safe.
as for the Crankcase Vent Valves, I'm just gonna replace mine for shits and giggles (seeing as how ECS tuning sells them for so cheap) and i have a feeling it may smooth my rough idle out I've not gotten ove ra cold winter. I'm sure the cold cold -34° C (-29° F) has made the rubber disc plasticky and has caused it to break finally.
Oh well, look slike a VERRRRRY easy fix
