1998 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.

The hi-amp alternator fuse at the firewall commonly shorts out; the shorted fuse could be mistaken for a bad alternator.
