I took BPT valve loose Sunday morning and found that the 90° hose to the EGR valve had a small hole in it. I took the hose off, wrapped it in electrical tape to plug the hole temporarily, and put it back on. I started the car 4 different times after idling for a few minutes. My codes haven't come back (yet). I'll drive the S14 to work tomorrow to see if they come back.
