Question about 2010 Mercury Mariner
After an oil change yesterday I started noticing a whistling noise when I accelerate. If I take my foot off the pedal it goes away and seems to stop above 40 mph.
Did you remove any plastic/metal splash shields under there to get to the oil plug/filter?
Make sure you put those back in correctly as they could catch air and make noise if put in wrong.
Other than that, I can't think of anything oil change related that would cause a whisteling sound.

I've seen that sound before. Check the transmission oil level. That sometimes causes a whining sound.
Hope this helps.

Sounds like a vacuume leak, use some carb cleaner in a spray can and gently spray the engine. When you find the leak the engine will stumble, check in that area for the leak.

make sure your vacuum advance doesent have a slow leak, attach a spare piece of vac hose to the vac advance mod on the distrributor and s u c k on that hose., it should hold air and not leak make sure you dont have any other vacuum leaks. the vac mod on the tranny could have the same problem. open the jets on the carb a little by turning counterclockwise, you see the engine mellow out. theres two screws up under the front of the carb might need a rebuild, fuel filter could be half clogged. and then re time the engine..

I would look at the half shafts or cv axles.
