I have a 1998 Acura integra that is running too rich. I have replaced the spark plugs and wires as well as the o2 sensor. Nothing seems to help. It is still misfiring and stalling when driving. Any ideas

Running rich could be caused by a bad O2 sensor, excessive fuel pressure (bad fuel pressure regulator or plugged return line), leaky fuel injectors, dirty air filter or restricted air inlet, or a defective coolant sensor that prevents the engine management system from going into closed loop mode.
