Question about 1999 Mercury Mystique

1 Answer

I just need it fixed! ASAP in Atlanta GA

I have a 1999 Mercury Mystique, 6 Cyl. When I crank it up it starts to make a LOUD humming noise for just a few seconds at a time until i pull off. And when it happens the gage (not the MPH but the other one) goes up a little bit and down when the humming stops. When I drive it humms but If i press on the gas to make it stop, it stops but when I start to slow down it will start up again.
When I took it to get a diaginosis there were a lot of electrical problems. I was just thinking i need to replace some of the fuses cause my dad had changed some and put some in the wrong place when trying to fix my window and the whole car didn't start.. But I don't have a clue!

Why does my 1999 mystique will crank and run but runs rough


Sounds like your idle valve has stopped working . Does it run fine when warmed Up? If so I would clean the throttle body and remove the idle valve and clean it. After reinstalling it have someone turn the key on while you tap the idle valve lightly with a screw driver Handel. Then see if it will idle when started. If it does then you need a new one.
