Take the intake hose/tube off the throttle body.
Start the engine
Using your thumb, block the top left hole inside the TB.
then the bottom one, if there is one.
then both
Does your idle change?

It's a two part problem. Your TB is letting too much air through and the EACV is not closing enough. The TB alone will not let the engine idle, but combined with the EACV they are letting too much air through. Take the EACV off and clean it with carb cleraner. That is a temporary fix, the bad idle will come back in a few days.
I always recomend getting a new one. If you don't have AC, then you could try blocking the EACV with a piece of gasket material and make two 1/16 holes to restrict air passing though it, and then sandwich the gasket between the EACV and the manifold.

Your EACV is blocked and you still get high idle?
Then the TB is the culprit assuming you don't have a vacuum leak somewhere.
The holes are to let some air through the EACV so the car can idle.
