Go to this website and pick owner guide on left task bar. Input vehicle info then get the owners manual.Your fuse panel info starts on page 120.

To replace lighter just reach around behind it and unhook connectors. The stick something in the socket(I usually use 2 fingers) and twist it counter clockwise. the center will screw out of the sleeve.

SOURCE: egr problem

Check the passages under the airhorn. When carbon builds up the diagnostic blames the EGR for not opening and throws a code. Actually there is no flow to the EGR because the port is clogged and the diagnostic measures the flow after the EGR.

They really needed to have a sensor before and after the EGR. Also remember to disconnect the battery for 10 minutes to remove old info.

How do I fix an EGR problem for a 1997 Mercury Mystique?


What you would need to do is find out which part is making the problem. By this, I mean the electric solenoids which supply Vacuum to the valve or the EGR valve itself or the EGR ports feeding the exhaust to be recirculated.

Free "check engine light" tests are available at major parts stores like Autozone.

You can test the EGR diaphragm by using Vacuum or by pushing the diaphragm open and putting your finger over the vacuum opening and sealing it off.

You may also have soot in the EGR valve prevent it from closing. Remove and clean the EGR.

My 2002 Mercury Mountaineer idles rough, I changed pugs, coil and also took it to 2 different mechanics. Recently the code came on for P1400 . . .Im just wondering can this be the cause of the rough idle?


Hi, if your EGR valve is stuck open, it could cause a rough idle. P1400 indicates there is a problem with the EGR flowmeter. This may be the result of a valve that is stuck open or may be the cause or may be unrelated. What I recommend is to first check the vacuum hoses on the sensor/flowmeter and also check the hoses from the EGR solenoid to the EGR valve and from the intake manifold to the solenoid. If those are good, remove the EGR valve and inspect the EGR passages for blockage. Also check the valve for properoperation. The valve should default closed and open when engine vacuum is applied to the vacuum port. If you cannot find anything wrong, with the valve or passages, test the control solenoid that supplies vacuum to the EGR valve. It should click open when you apply 12 volts to it. If all this is good, check the wiring from the flowmeter to the computer for continuity. Please let me know if you have questions, and thanks for using FixYa.

1997 mountaineer check engine light on again have already replaced all o2 sensors egr valve and a pressure something light kept comming on finally went out almost 400 miles later it has come back on


Assuming everything you replaced was bad,and I doubt it,you would have had a different code for each item you replaced!

What code do you have now?

It sounds as though,your replacing the parts, that are the symptom ,e.g. codes,not finding the cause or problem ,that set them.
