There was a loud whistling noise coming from the engine compartment and the car die, my question is do coil packs make whistling noises when they malfunction?

Leaking Vaccum Line or the intake system has a leak between the air filter housing(air box) and the engine's throttle body, that's usually the culprit!

Possible vacuum leak from one of the hoses causing unmetered air to enter the engine. Look under hood in engine compartment and listen for noise to see if it may lead to a disconnected/collapsed hose resulting in a vacuum leak and repair/reconnect as necessary

yes could very well be an exhaust leak.but that should be kinda loud and annoying..also u could have a slight whistling sound coming from ur air intake hose coming from air cleaner box to ur intake or throttle body or ur air inlet goin to the motor. when the motor is accelerated it would produce a high pitch sound like a whistling .hope this can help

You have to diagnose an ignition problem,
since you have the PO300 & misfires shown,
at least for many cylinders

Could end up just being one cylinder or several
that need whatever ignition parts control them

Individual Coils for each cylinder or a module that
applies to all of them

Wouldn't use the car until resolved
As it gets worse, you will ruin the exhaust converter

No idea on the whistle

Checking Window Seals - The window seals (weather stripping) in your car are used to seal the water and wind for entering the passenger compartment. When these seals fail from damage or are eroded by the weather they can allow wind noise to enter the passenger compartment. This failure can cause a whistling noise as the car is driven. Some noises are only present when the vehicle is driven at certain speeds such as 55 MPH. These whistling noises can be difficult to find since you are driving at the time. Have a passenger help with the diagnosis by running their hand along the area the noise is being generated from. Once the noise source has been located replace or repair the failed seal and recheck.

Hi,
A whislting noise would make me suspect a cracked or broken vaccuum line. Whistling as it sucks air into the system. I would check the biggest one first, on your brake booster. It is a large line coming from the engine to the brake booster assembly located behing the brake master cylinder. I would check all the lines with engine running, have a helper rev the engine slightly while you listen in the engine compartment to see if you can locate it. Also work the brakes simultaneously. Cold weather can make older lines crack which can cause a serious problem depending on which line cracks or breaks. Check all your air lines first and see if you find it in that system before assuming something more major. A crack in other engine system lines will usually produce a fluid leak of some type.....Good luck!..Mike

a whistling noise will be a vacuum leak from some point. The Escapes are known for having vacuum issues in the rear of the engine due heat caused from the motor. The lines dry and crack out.

Yep...try replacing your coil pack....

try and look at the belts, if they are wore out replace them

Troublkeshoot possible noisy idler pulleys, if they are OK, remove the plastic cobers & check for a noisy timing belt tensioner pulley. Water pumps rarely "whistle"; they grind. But, if you see any evidence of leakage at the weep hole on the water pump impeller shaft, replace the pump regardless. Might as well replace the timing belt whilst you are there, too.
