Sprayed mine with throttle body cleaner only (no WD40) about 7 years ago. Not been a problem since. Used about 2/3rds of the can at the time (Not all at once). Beats taking the intake off to get it working again if you can do that.

Glad to hear others have had long term success. Some do, some don't. I did the spray and within a few months the codes came back. Last summer I changed both valves and *knock on wood*, no issues since.

Had the code, tried the spray cleaner MANY times to no avail. Replaced both valves.... drivers side, easy. The passenger side, I moved from the back of the head to the passenger side, near the plugs. All well now.
