Here are some possibilities: Cats are gone, ACV is not injecting sufficient port air (ACV, Air Pump, or switching/releif solenoid valves defective), or too much fuel at idle (leaking injector, misadjusted idle mix adjust screw). Could also be bad water temp. sensor. That should get you started anyway. Good luck!
