one more time. What most people do is start the engine and take a can of R134a, with correct hose and valve see NAPA or Autozone, and spray the 134a on and around the intake system. Once you hit the leak the idle will drop as R134a is a really great fire extinguisher. You can use propane to do the opposite, the idle goes up, but the risk of explosion has always turned me off to this method.
