The whistling sound could be one of a lot of things from a piece of debris attached to the belt or a pulley, to a major vacuum leak. With the engine light being on take it to a local parts house and ask them to retrieve the codes. Once the codes are retrieved the parts house should be able to tell you what more is wrong with it. Go from there.

A broken or loose vacuum hose is more than likely the case. Also check the air inlet connections. That can be loose as well

What does the service engine light mean on a 2015 Ford Edge


Service Engine Soon

If the Service Engine Soon indicator light stays lit after you've started the engine, the On Board Diagnostics system (OBD) has detected a malfunction of the vehicle emissions control system. Contact your authorized dealer as soon as possible.
If indicator light is blinking, an engine misfire may be occurring, which could damage your catalytic converter. Drive in a moderate fashion (avoid heavy acceleration and deceleration), and have your vehicle serviced immediately.*
The Service Engine Soon indicator light illuminates when the ignition is first turned on (prior to engine start) in order to test the bulb, as well as indicate whether the vehicle is ready for Inspection/Maintenance (I/M) testing.
Normally, the Service Engine Soon light will stay on until the engine is cranked, then turn itself off if no malfunctions are present. However, if after 15 seconds this light blinks eight times, it means that the vehicle is not ready for I/M testing.Check this link out Gary.

How can I determine with certainty the cause of a Service Engine Soon light?


Personally I would do a complete engine service, for example Air and Oil filters, Oil and Plugs (it may also be worth changing the coolant as I am not certain of the parameters that are monitored by the system) If the light still remains on then the most likely problem is the Engine Managment Unit or a sensor.

My 2000 dodge neon at red lights or stops will start to sputter or **** like its going to stop i've just about put everthing new on it new head gasket,spark plugs, plug wires, distributer, battery and it...


Scott, this might sound strange but check the wiring harness just in front of the AC compressor, sometimes, this wiring harness will come loose from it's tie down and start rubbing on the AC compressor pulley causing all kinks of electrical glitches intermittently. Remember, your Service Engine Soon light is for Emissions only, it will stay on only if your car is polluting. Good luck, Gary

Blue smoke but no lights on the problem


blue smoke on startup is generally from worn valve guides or bad stem seals on same (not really terrible as long as it stays the same) It will run rough for a minute 'till the oil in the cylinders is cleared out. Service engine light is pretty much on its own timer and does not mean anything but it's there to annoy you into going to the dealer. If O2 sensor was bad, it would eventually put the red check engine light on.

Service Engine Soon Light comes on but doesn not stay on.


If your battery starts turns the engine over, it is doing it's job well. It sounds like your engine computer is not liking the cold engine. If it has been a while since a tune up, it would not hurt to go ahead and do it, but if it runs ok after it warms up, I sould not worry about it a whole lot. When the engine is cold, the egr valve and other things that are made to limit polution tend to stick and give the computer bad readings. A serious tune up may fix it, and I think should, but you MAY still be in the same boat! That does not FIX it for you, but should ease your mind on the light.
