2000 Mazda Millenia Problems

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.

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.

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.
