Ditto with judge. Have you checked the fuel pressure and delivery rate?

You didn't mention a "Check Engine" light. Is it on? A disconnected vacuum hose on the regulator would cause the fuel pressure to rise (low vacuum=high load=high fuel pressure requirement). I would want to look at the data stream. Particularly at the Long term Fuel Trim (both banks) and the Mass Airflow Sensor (MAF) readings. Could be a fuel pump problem but not likely a regulator concern. The Fuel Pressure Regulator on this vehicle also measures the fuel pressure and temperature. A good scan tool will tell you what you need to diagnose this one. You can compare the fuel pressure reading to the fuel pump duty cycle to see if the pump's doing it's thing. (P.S. - I see "dusted" MAF sensors all the time in our fleet of Police Interceptors. I don't try to clean them anymore - I just change it out if it's bad) I've experienced one other concern with this one and hopefully, it's not your concern too - the engine harness from the processor to the engine can have a break in the 5 volt reference wire just behind the left valve cover. I've seen a couple of these now. Not many, thankfully.
