I am sorry I cannot offer an answer to this as yet just to commiserate. I too have a 2000 millennia with under 80,000 km and the same malady. Is it blue or black smoke? Oil is leaking into the screw chamber on the supercharger,an early sign of failure.Another sign is oil pooling in the intercoolers.
a Mazda millenia with a miller cycl engine 2.3 engine has 6 igition coils
The millenia P - has 2.5 liter engine, The Millenia S has a 2.3 liter engine
remove the plastic cover that says miller cycle engine on it. right about where "engine" is, you will see it. it has a gold dashpot with vacuum lines
The 626 and the Millenia share the same 2.5 liter engine,the only difference being the version in the millenia makes more power.
The Supercharged 2.3 liter will have a large piece of black platic over the top of the engine that says "MILLER CYCLE ENGINE" in large green letters and 2 small air-to-air intercoolers inside the engine compartment.
2.5L V-6 Mazda Millenia engine is a non-interference engine. If your timing belt pops, you will not damage your valves, like I did in my Diamante
how many oxgen sensors on a 1995 millenia

Depnds on the code
I have a 2002 Millenia-S and removing and reattaching the + battery cable does reset the check engine light.Answertry unhooking the positive cable to the battery...this works on my 97 millenia
AnswerAT the engine end of the upper rad hose.on a millenia, the thermostat is inside the flange on the engine side of the LOWER hose. look under the coolant resevoir. see the lower hose? follow it to the engine. where it connects, that is the cover for the thermostat.
