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.

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.
