My codes (OBD1) aren't as specific. To me, this would sound like the charcoal canister purge solonoid is stuck in the open position. It COULD also mean you have a vac leak.

Sticky solonoids happen like the *****. Sooner or later, you'll have it, and it'll probably go away.

Keep an eye on it. It'* not a serious issue.

IN the solonoid. Some WD-40. Squirt into the incoming and outgoing vac ports. Then immediately go for a drive.

You might want to clear the code first, then watch for it to return.
