1999 Mazda Millenia ProblemsRough 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 (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.
