The canister on my 88' 900 has an issue. One of the previous owners plugged the vacuum line going into the canister, from the inlet manifold. The fuel fume line is still connected, but the other(to the inlet) is just plugged. If I connect it correctly, the CEL light comes on after idling a few minutes. What might be the problem here? Is it alright just to leave the thing plugged, and have the canister vent out from it's location?




Thanks

You probably have a bad Purge Valve on the canister. Leaving it plugged as it was causes a tiny amount of excess unburned hydrocarbon pollution, but not enough to bother one's conscience.

That's what I figured. It was probably creating some kind of air leak when it's connected correctly. I'll just leave that hose plugged up so the CEL stays off. No big deal.


Thanks Jim!
