Why does your 2001 Mazda Millenia S with the Miller Cycle engine and only 51k miles need coil pack replacements?

heat seems to be one of the weak points of the millenia cop system. generally, the right bank coils go first. also, oil in the wells can cause the coils to short out and die. my personal favorite is all the dummies who change their spark plugs, and put iridiums in there. even tho the gap is WAAAY off, they believe the aftermarket parts person OVER the dealer, and put the wrong plugs in "because the parts guy at autozone said they would work". the bigger gap makes the coil work harder, overheat, and die. if the plugs have not yet been changed(Mazda says every 60k) then my money is on oil shorting out the coils. and it is really rare that it would need all 6.

Where is the air bypass valve on a 2000 Mazda millenia code 1540?
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
How do you know if your Mazda millenia has a 2.5 or a 2.3 engine?
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.
Advantages of the Miller cycle engine?
The Miller Cycle engine has a very flat torque curve, with maximum torque achieved at 3500 rpm, as compared to Otto Cycle (standard 4-stroke) engines which generally require 4500 rpm or higher. Due to this lower-end torque ability, the Miller Cycle engine is capable of moving much heavier loads at a much lower fuel economy.
Where is the abv in Mazda millenia?
pull off the plastic cover that says miller cycle. the abv will have a yellowish vacuum "hat" on it, right below about where the 'cycle' word is. if your miller cycle cover is missing, then the abv will be on the back(driver side) of the engine, right in the middle. at the very end of the intake. you will see the yellowish vacuum dashpot on the end of it. but, that valve never goes bad. if you are getting 1540 codes, it is most likely vacuum or vent circuit/solenoids(p1525/1526)
What would cause a rough idle on a 'warm start' on a 2002 Millenia with Miller Cycle engine with 68K?
bad coil(cop hates heat, coils short out when hot) bad gas-vapor lock bad fuel pressure regulator bad drainback valve, no fuel in the rail
How easy is it to change a knock sensor in a 99 Mazda millenia and what would it cost to take it to a mechanic?
if its a miller cycle engine its a nitemare 5.2 hours labor It's under the supercharger support bracket.5.2 hours is a rather anemic estimate as it took me almost that long to get the CAC assembly off.
How many catlytic converters does a 1999 Mazda Milena Miller Cycle engine have?
Only a cyco freak knows that. 5.
Why my Mazda Millenia 2000 with Miller cycle engine is taking in oil and produces heavy smoke when first turn on the engine in the morning .?
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.
What is the firing order for a miller cycle engine?
Be more specific. What is the make, model, and year of the vehicle you are referring to. Not sure if they are all the same.
What is the cause of bad hesitation only at high RPMs on the 99 millenia with the SC Miller Cycle engine could it be a fuel filter?
I had an 01 Millenia with a similar so you may want to track down the following: Check that the distributor is intact and properly sealed; check all spark plug wires and the plugs themselves; If the check engine light is on get the code read. My Millenia ran fine at city speeds but as soon as I would get on the highway and accelerate, the car would begin missing and losing power. My distributor ended being cracked and the spark was escaping and not making it to the cylinder. Good luck! The 2.3L has coilpacks,no distributor. If it was a fuel filter it would cause hesitation at lower speeds as well.
What is the spark plug gap on Mazda millenia?
2.3(miller cycle) is .7-.8mm(.028-.032in). 2.5 is 1.1mm(.044in). spark plugs with precious metals tips are NOT regappable. they come with the correct gap from the manufacturer. if the gap ain't right, it's the wrong plug
Is a Briggs Stratton 6.75 engine a four cycle or a 2 cycle engine?
