Hello i am new to the forum. I have a Crown Vic Police Interceptor that i bought about 3 months ago with 40,000. The car now has 44,500 miles on it. Anyways haven't had a lick of trouble with it until now. The car still runs good but whenever i first start my car in the mornings in the cold weather it makes like a humming noise. I can give it the gas and then it'll appear to go away. Then i put it in drive and the hum comes back. Whenever the engine warms up the hum seems to quit. The check engine light has also been on for like the last month or so. I brought it in to Auto Zone and it shows a code of "emissions" Can anyone please help me figure out what may be wrong here? Thanks in advance!!!
