#3646 of 4030 Mazda Millenia 2002: Miles per gallon
May 02, 2006 (3:39 pm)
All - my millenia 2002 is a very reliable car except for two things:
1. Miles Per Gallon: I have NEVER gotten more than MAYBE 23 MPG, I'm more like 20 MPG typically. I do a lot of city driving but I also do longer distances (being in austin, tx this is easy to do). i still never break 23-24 MPG. I think this is a load of bull and that mazda is falsely advertising 27 gallon on the highway.
2. Airbag light - my airbag light constantly flashes intermittently. mechanics can't seem to figure it out.

We have discussed milage a number of times on this forum. If you go back and do some reading you will find that the MM is not a gas hog, but it is also no econobox. Weighing close to 3700 pounds, it has quite a bit of weight to carry around in great comfort and near luxury including automatic climate control.
My personal experience on long trips as well as being in a 5 hour traffic jam in Orlando as well as a two hour one in St Louis give these approximate results.
Flat out highway cruising gives about 27 mpg which includes mostly 80 mph all day driving on interstates. The parking lot speed traffic jams still yeilded about 20 mpg, which I thought was quite good for mostly going nowhere at about 5 to 10 mph. Overall my average is about 22 which is mostly local rural town and state highway driving in central Florida.
It appears to me that Mazda is not stretching the milage truth. All in all the milage on my 2001 MMP which has the 2.5L normally asperated engine, is about 5 mpg better than my wife's car which has a 2.4L straight 4 and is an American product. I like her '39 Ford looking hatch back just fine and it is very handy. But the MM is definitely superior to it in every way but cargo hauling.
It doesn't take a Mazda dealer to work on air bags. I'd suggest going to an auto electric shop where they actually have experts in electrical work.

Hey all. I want to say first, I really appreciate everyone responding to all the questions that people ask. Being that i just bought my car, hopefully i will be able to help on these in the future. My question today is this. My engine light is on and my gas mileage is horrible. Is the best way to find why the engine light is on by going to a AutoZone? Do they have the equipment to check the computer? Is there a chance that it is a catalytic converter? And if it is, do you need to go to the dealership to have something like this done or can you go to a normal mechanic? You can buy a new converter on ebay for about $60. So just having it put on must be time consuming and costly. I know that this car had one converter replaced. Might need the other one now. Thanks ahead of time.

My check engine light pretty much stayed on for the first 1 1/2 years I had my 2000 Millennia Milennium Edition. The diagnostic kept reading "Misfire at the 6th cylinder." So far, I've had CO2 sensors, catalytic converter, spark plugs and a coil for the 6th cylinder and most recently a fuel injector kit. The coils were moved around when putting on the fuel injector, so then the Misfire was then at the 2nd cylinder, which indicated that the new coil I had put on was malfunctional. This has since been replaced and the check engine light has not come back on yet, however, now I smell strong gas fumes in the car and still getting about 12-15 mpg (Premium unleaded to boot!) I love the car and know it would be great fun to drive, but I'm so frustrated that I cannot really enjoy the car. I've put more money into this car in the past 1 1/2 years than I had put into fully loaded cars that I'd kept for 5 - 8 years. If you find a solution, please post it. I'm willing to do most anything.

I have an '02 S and I get 23mpg's in town and I average 27 on the highway. My highway mileage has ranged from 25 to 31. The 31 was doing 65 mph. Doing 75 - 85 is when I had the 25. Though on trips it has averaged 27 overall.
#3651 of 4030 Cylinder misfire
May 04, 2006 (7:02 pm)
According to the repair manaul for the 2002's S model, since you said you are using premium unleaded, are as follow:
1. Spark plug malfunction
2. High-tension lead malfunction
3. Fuel injector malfunction
4. Air suction in intake-air system (between dymanic chamber and cylinder head)
5. Inadequate engine compression due to engine internal malfunction.
6. Related connector or terminal malfunction
7. Related wiring harness malfunction
These are only possible causes.

Thanks kcm8419. I'll pass this along. I know that I've replaced the fuel injector and spark plugs, some coils, CO2 sensors, and I can't remember what all else off the top of my head. I would just love to get the problem resolved. When I tell the dealerships and various mechanics the type of gas mileage I get, they all just say "Well you have a supercharged engine" and they don't get good gas mileage. I have done lots of research on this car and the general consensus is the same type of mileage that you get. I hate when they use that "supercharged engine" excuse. Part of my problem is that even at some of the Mazda dealerships don't know a whole lot about the Miller Cycle engine.

I thought a couple of years ago someone on this site said they were having problems. They eventually found a vaccuum hose plastic tee had broken and once they replaced that they said the car ran fine. So you might want to check for one of your vaccuum hose either being off or cracked/split. I know this could be a headache but it is worth a look.
#3654 of 4030 CEL and main computer
May 06, 2006 (1:11 pm)
I own a 95 S with 167,000 miles. I purchased it in 98 with 62,000 miles. The car has been fair as reliability is concerned and great for performance. I have had the CEL come and go at least 8 times over the years. First it was the O2 sensor, howver when the mechanic checked the O2 sensor seperately the sensor was fine. My mechanic recommeded changing the main computer in 2001. He worked as a senior mechanic for Mazda and diagnosed that some of the main computers have a malfunction and send out codes in error. I believe that this was the problem for my car, secondary to the three oxygen sensor codes that were false. It cost me about $900. Since the change I have only had the light come on once at it was for the knock sensor about a year ago. I think this is a Mazda problem from all of the post with frequent CEL warnings. Love the car and I get 22-24 miles per gallon at 65-70 mph.

That's pretty much exactly what I get on 01 S.
