There are some products, for direct injection valve cleaning, in a spray can that are made for spraying into the throttle body. You could just use one of those if you choose, rather than using the pressure sprayer, but you can spray it into the IAT hole instead because easier than separating the TB hose from the TB. You'll want to seal the gap between the tiny straw and the IAT hole so it runs better. Then when it's done, you'll have a CEL, but it will clear itself...if for some reason it does not...you can have it cleared. Don't forget to have the engine warmed up to running temps before beginning.
