Mercury Mystique Problems
The Check Engine Light can illuminate with codes due to the lack of EGR (exhaust gas recirculation) flow caused. This is commonly a result of a clogged passage in the intake manifold. To correct this problem, the EGR valve has to be removed and the passage cleaned thoroughly. Partial restriction of this passage can cause smog test failures for the NOx emissions without causing a drivability symptom.
If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.alternator fuse at the firewall commonly shorts out; the shorted fuse could be mistaken for a bad alternator.

This is a great car. I have owned this used Mercury for a year now and it is in great shape it almost has 130,000 miles on it and only needs basic maintenance. Like fuel filters, oil changes and a tune up.
