OK, now my mechanic who i'm quickly losing faith with has sias this car has a gas preference. Last time a i checked cars don't know the difference unless this one has feelings, which i doubt. Anyway this is a fairly new car and everything else is working great, so what should i do to fix this car. My guess was the fuel pump, but with my luck it's probably not. The whistle is high pitched and a bit lobsided sounding. It also seems to struggle to maintain an idle. This problem is persistant and fairly frequent. The stalling isn't as frequent, but it is rather jumpy. That's pretty muc the problem. Any suggestions would be great. on what this could be so when i take it back to my mechanic i can ask him to check it. Thanks

Stalling, and a high pitched whistle or hum, check the Idle Air Control valve, common problem on the Taurus, this controls the amount of air to the engine when you have your foot off of the gas. Some valve rattle under a load is normal on the 3.0 OHV engine, because of the pushrod design, but only under load, such as in overdrive up a hill. If it is more than a very light rattle, check for a contaminated Mass Air Flow sensor, and have it cleaned. If you are having a surging problem at idle when you first start the vehicle cold, or the idle dips or stalls when first started cold, there is a Powertrain Control Module reprogram for this concern available only from the dealer that should improve it.
Update, Neither the IAC nor the MAF sensor will set a diagnostic code for this type of symptom, if the MAF is dirty it will still be getting the same signal voltage but the return voltage will be skewed, the PCM will never see the problem. Scanning doesn't solve the problem, just tells me which area to look at.

well for the stalling problem its a sounds like its running out of gas, which can be anything from bad fuel pump to broke or burnt electrical connections. you may have come across some bad gas, you may have a bad fuel filter , which personally i would change first..
could have a sensor that acting up causing it act up,
as for the rattling noise it could be anything you just have to look around and see if anything is loose
as for needing special gas i doubt it needs it
i think you may have some bad gas in the tank

They use to use gerbils running in a wheel to power cars, but now with the high performance and faster cars they went to greyhounds.
Lift the hood and check your dogs toenails, maybe their clicking.
Seriously; have your mechanic do a fuel injection flush and change the fuel filter. Then run a FULL tank of High Octaine gas.

i own a repair shop,and before you go spend a whole lot of money on it,,you might want to check the gas filter ,i had an 05 model in here that was doing that ,and it that new it needed a new filter on it,even i was surprised at this one being bad,and it was dong exactly like yours is doing now,it may not be the filter,but its a good starting point ,and you may also want to look for a vacuum leak on it,i hope you find it,,good luck.

Actually, the mechanic is right, there are certain cars that need a certain type of gas. My father has a ford focus and I know his needs the most expensive kind. A diesel truck needs diesel, not gas.

All these guesses and not one suggestion to scan for trouble codes. I would do that first, may solve the whole problem.
