Seriously? A 6ft vacuum line, a bottle of spray throttle body cleaner, and about 30 minutes of spray time while the car is running and you foot on the throttle... about $10 bucks. Keep mind that most of the build up can easily be removed by TB cleaner, but you can't just spray into the engine without it running. Otherwise it will flood the engine and the removed contaminants won't be burned off. Plus with the engine at part throttle, you'll effectively increase the force of the spray further helping with the cleaning process.
I guess I need to do a before and after shot for everyone. The annoying part is that typically I wouldn't need to remove the intake. In this case I would have to remove it twice just to show the effectiveness.
