Sounds like a fuel leak in the upper intake. Fuel pressure regulator, spider fuel distribution block, poppet valve stuck open or leaking fuel line...depending on the model year will depend on what parts are involved...

The best way to test for an internal fuel leak is to use a fuel pump pressure tester. Run the engine with the tester installed, then shut off the engine and watch the guage. It should hold residual pressure. If it drops to a very low pressure in a short period of time, it has an internal leak.
