Can be a vacuum leak which usually causes higher rough idling,but a dirty MAF sensor or dirty Idle control can cause it. don-ohio (:^)

SOURCE: high pitch squeaking noise at idle

you might need a stethiscope to hear where this is coming from could be a idler or maybe the tensioner or maybe the alternator .. none of these would bother power

SOURCE: 2001 Mercury sable bad idle

CHECK THE PCV VALVE HOSE THAT CONNECTS AT THE BOTTOM OF THE THROTTLE BODY, THESE HOSES ARE KNOWN TO DETERIORATE AND ALLOW UNMETERED AIR TO ENTER THE COMBUSTION CHAMBER, WHEN THIS OCCURS THE OXYGEN SENSOR'S SIGNAL TELL THE PCM TO INCREASE THE PULSE WIDTH OF THE INJECTORS CAUSING THE VEHICLE TO ALMOST STALL.

SOURCE: 1999 Mercury Sable Dome Light won't shut off

Next to the headlight switch is a dimmer dial for the interior dash lights... if you turn it all the way up, the interior lights remain on... there is a "detent" on the dimmer. turn the interior dash lights all the way full on ...you'll feel the detent, then turn it down back past the detent a little bit...that should cancel the interior courtesy lights... wait a bit because the interior lights are sometimes on delay timers....
good luck let me know what happens.

SOURCE: mercury sable 2001 duratec engine DOHC I get check engine light and diagnostic code PO401". Any suggestions?

Barring any vacuum leaks, P0401 is indicative of a bad EGR valve. Hope this answers your question. Best of luck.

High idle


Vacuum leaks or fuel pressure, or ECM.
When you press the accelerator you allow more air into the engine. The same extra air can get into the engine through leaks in the Vacuum system. Sometimes using a spray bottle of water and spraying the seams of the Intake manifold on a running engine can reveal the opening. Also spray any Vacuum lines and the Brake booster. A leak will change the RPM.
A high fuel pressure can cause an increase in RPM.
ECM- has a lot to due with timing and fuel demands.
Binding Linkage. Disconnect the throttle linkage and see if the RPM drops. If it does not, shut off the engine and work the Air horn Butterfly and check for smooth operation. It is possible that a mounting screw on the Butterfly shaft has slipped and the flap is binding or dirty.

How do I bypass neutral safety swith in a 2001 mercury sable


If the engine will not crank in park or neutral, you may be able to jumper the brown pink and the tan red wires at the switch. I would not jumper them with the switch connected in the circuit.
I am assuming you have already checked the starter relay.

What is the problem of high rpm of mercury sable


You see the vacuum hose solution by Shadow Gilbert? This still applies.......but usually if it's a vacuum leak,the engine will run a little rough.
Could be you need to remove the solenoid IAC in the aluminum duct that has the throttle control close by.
They actually make a special spray to clean this and the holes it works thru.
Also, you have what's called a MAF sensor,and these need the tiny wires inside gently brushed off and sprayed clean with electrical contact or what I use is brake cleaner spray.
Something that leaves NO residue.

I have a 2002 mercury sable it will stall out unless I put it in neutral and give it gas when stopped at a light or slowing below 1000 rpm. What could be the problem?


Idle air control could be stuck. If so clean it with some carb and choke cleaner. EGR could be stuck partly open. If so clean that or replace it.

Hi, the cause of this problem might be a faulty fuel pump. As soon as the engine is under load the fuel pump can't keep up with the demand and cause a misfire
