2h intake manifold and butterfly cleaning, best way?

[sodafeld1]

The best way I guess is to remove the whole intake manifold to insure carbon and blowby doesn't enter the injectors.

Is there any type of super duper spray one could spray when engine running?

I guess it could be be a quick way to clog injectors though.

Anyone used the liqui moly diesel intake cleaner? Idling in city traffic is the soot culprit..

when I think about it, injectors should be ok, crud would enter chamber and burn. I don't have much oil and soot in there but enough to make the butterfly a little sticky..

They are always a bit oily in there.. no big deal. I never clean mine.
