Mercury Mystique Problems

Problem With Idle Air Bypass Valve May Cause Engine Performance Problems

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.

Hi-amp alternator fuse at firewall may short out
The hi-amp alternator fuse at the firewall commonly shorts out; the shorted fuse could be mistaken for a bad alternator.
Check Engine Light Due to Plugged EGR Passage

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.
