So my message is that the right chemicals can do a job, maybe not the perfect one, but very good one.
And no reason to make perfect one if it will be messed up up after first thousand miles.

LOL OK. Yea, I cleaned my swirl flaps and throttle body too, you have to since you have no other option. You can't media blast them. The oil sludge on the flaps is not the same hardened carbon found on the valves. Did you clean your intake, intake runners or valves? Please post pics of your valves.
