1995 Mazda Millenia Problems
Excessive Oil Consumption Due to Supercharger Oil Seal Leak
The oil seals on the supercharger can fail and cause excessive oil consumption and bluish gray smoke from the tail pipe. Supercharger replacement is commonly required to correct this concern, this can also be an expensive repair.
Check Engine Light Due to Restricted EGR System
The passages for the Exhaust Gas Recirculation (EGR) system can become restricted or clogged causing the Check Engine Light to illuminate. The EGR valve will need to be inspected and the passages cleaned.
Rough Idle Due to Broken Vacuum Tee
There are T-shaped vacuum connectors under the intake manifold that can break and cause a rough idle.
Misfires Under Load
Misfires under load (acceleration) can be caused by the valve cover gaskets leaking oil into the spark plug wells shorting the spark plugs to the cylinder head. New spark plug wires will be needed and the valve cover needs to be resealed.
