Check for a very dirty or clogged air filter, faulty Manifold Absolute Pressure sensor (or Manifold Air Flow sensor), disconnected or faulty Engine Coolant Temp sensor, disconnected or faulty Intake Air Temp sensor, and leaking fuel injectors or a stuck open cold start fuel injector. A pinched or blocked fuel return line from the fuel pressure regulator to the tank is rare but could also be a cause.
