Take off the throttle body hose and verify that the throttle plate is closing.
Adjust the throttle plate screw and nut so 2 threads show.

Completely block off the opening to the intake plenum by cold start injector.

Pull connector out of throttle position sensor.

Using a spray can of brake cleaner, spray inch by inch the entire intake.

You are looking for vacuum leaks at the gaskets in the intake manifold and vacuum leaks at your injector seals.
