Mercury Mystique ProblemsCheck 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.
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.

I replaced the vss beacause my car was skipping and jumping around the car only has around 43000 miles on it so the trany wasn't the problem so my next guess was the vss I replaced it and now my speedometer will not work
