high idle after fuel injector swap

I just changed my fuel injectors to the ford injectors and now my idle is at 2k. What would cause this and how would i go about tracking it down?

possible vacuum leak, You can carefully spray carb cleaner near all the injectors and hoses, see if the idle changes any. It is a flammable spray so you need to be cautious.

Likely knocked a vacuum line off--check the MAP to TB line that is most common.

Worst case could be one of the injector o-rings is out of place.

With a big RPM leak I prefer a household pump spray bottle with water set on "stream"--you hit the leak and the engine will choke down quickly.

i retraced my steps and it was a vacuum leak. I didnt attach everything. Thanks guys.
