Had the E8 code years ago and had the purge valve under the plenum replaced. Code went away and did not come back for almost a year. Now it comes months at a time
. I believe whatheheck, a member on this board posted that there is another part that is worth replacing down there. The plastic part that connects the two vacuum hoses sustained a hair line crack triggering the E8 code. There is a post on here with pics for more details. I just don't feel like messing the thing right now. If I had known ahead of time, I would have replaced the plastic nipple along with the purge valve. I also replaced the gas cap, but that did not help.
