Default Idling high after round of injector cleaner

My mechanic friend and I recently ran injector cleaner through my 87 GT AOD and I've noticed the car seems to run a lot better. The only issue is now, for some reason, when in park the car is idling at about 1250 RPM. When I drop it into gear the RPMs will drop to about 900.

I let it sit over night and after starting it up the RPMs went to 1250 (it was a cold start), but then settled at about 900 in park. I figured the problem was solved, however after driving it for about 15 min and putting it back in park, the car was back to idling around 1250 RPM! Anyone have an idea as to what's going on? The car is running great, it's just that since we ran the injector cleaner the idle is a bit high.

You cleaned a bunch of bull**** out of your throttle body neck, intake plenum...

It can breath better, thus it can idle easier...

Just adjust your throttle body down to where you want.
