Question about 2001 Mazda Millenia

1 Answer

I recently purchased a 2001 Mazda Millenia. It was a little jerky test driving it, but it was winter with snow and ice. Now it's spring, and it's still jerky. I took it out on the hwy doing about 70 mph and the jerkiness was serious. The tachometer was a 3000 rpm and dropped to 2000, the speed dropped to 45 even though my foot was on the gas. The engine light came on. I drove another 1/4 mile or so, jerking, then stopped the car for about 5 minutes. I turned around and drove home (15miles) and there was no jerking. Another time, a similar story, 70 mph after 10 miles, but not as drastic jerking. I have taken it to the shop, they changes a dirty fuel filter (filled with sludge, they said). The computer test had shown low o2 and the fuel filter change was supposed to fix that. I continue to have the same problem, just not as drastic. What else can it be? I use premium gas.

Do you notice does the problem seem to worsen in rain or humid weather? Try checking the MAF sensor it may just need to cleaned it can cause problems like this. Be sure to use MAF cleaner nothing else. The sensor may also be bad but try cleaning it first, its cheap and only takes about ten minutes.

    Not only does the mass airflow sensor affect the performance of the car, I would also look into seeing if the o2 sensor is dirty.
    This can cause sluggishness, shuttering, and stumbling of the motor on take off.

    Also, it is possible that there is some debris of some sort in the gas tank that is interfering with the flow of fuel from the tank. Have a good mechanic blow the fuel line out with pressurized air, as that might dislodge any pieces of dirt that may be present.

    Next week, I will return to the mechanic and ask him to check to o2 sensor for dirt/debris. Thank you.

Why won't it start?

hit a patch of snow. you ran over some snow or the car did a major jump in the air from hitting the snow? If the car had a major thrashing around then it could be any electrical connection that runs the engine .

Winter driving tips.

As a mechanic and a shop owner I get to try out various types of vehicles during test drives. So we get to try out different types of tires too. We learn what works well and what doesn't.
Don't kid yourself, all season tires don't come close to a quality winter tire on ice and snow. And when you add studs to a winter tire it makes them incredibly good. I hope they allow studded tires where you drive.
All season tires work well when they can contact the road surface directly, but when isolated from the road by ice and snow they just don't work. The compound of the tire is generally harder to resist summer heat that wears tires out and with the colder temperatures they just get stiffer.
The winter tire compound is a little softer which allows a better contact patch with whatever is under it and the larger tread gaps pinch the snow to gain traction.
Another big misconception with tires is putting them on the drive wheels only.
OK, why not you ask? Well lets start with one of the most common vehicles on the road today, a family sedan, front wheel drive.
On these cars your engine and transmission is front mounted, so a good part of the weight is front biased. So that puts lots of weight on your front wheels. Weight =traction, right? So you put your winter tires on the front and your already used all seasons on the back.
Imagine now cruising down the freeway in 4 inches of fresh snow, "man these winter tires are awesome !" But you need to brake in a hurry for a deer coming out. Well those fresh winters do their job OK but the lightweight back end of your car hasn't the traction to handle the maneuver, the back end is sliding around sideways...hang on to it!!!
Well you get the picture now. You need all 4.


How many times do you see it each slippery day? You know, the drivers wheels howling for mercy as they attempt to accelerate.
Many vehicles today are equipped with traction control, there is a good reason for this accessory to your vehicle. If you can accelerate without spinning you will get moving faster than someone who is, and under more control too. A spinning tire will often create a hot spot under itself, melt the ice or snow and make it even more slippery. You even run the risk of getting yourself stuck in the rut you create.
A spinning tire also will go sideways easier, as it loses traction it also loses some direction.
Granpa said to me sometimes...slow down and go faster ...I now have seen the truth in it.

What type of tires would you recommend for winter driving?

Winter Tires

Better Starting Grip in Icy Conditions.
A special Winter Flex Compound, specially formulated to maintain its grip under the most extreme cold-weather conditions, including snow and ice, to help deliver better starting grip and shorter stopping distances.

Better Traction In All Winter Conditions
Cross Z-Sipes Technology uses a specially designed curve that locks the sipes in place, helping to provide improved grip on snow and ice. And because the sipes are full-depth, their grip lasts winter after winter.

My 2007 Mazda3 is the worst car I have ever driven on snow and ice? Is this a common problem and can anything be done about it?

First,any car that has low ground clearance can be a problem in deep snow. But the problem you are facing is probably related to the contact patch of the tires. If you have wide, flat tread, go-cart/race track style tires you will have problems in rain, on ice , and on snow. I am guessing you have too much tread on the ground for the weight of the car. You can try adding weight to the car ( sand bags in the trunk , it works for pick ups). I live in Minnesota. For one car I had to get narrower tires and rims ( about 2" to 3" narrower) for winter driving. It made all the difference in the world. If there is a different tire offered for your model that is narrower( off of the less sporty version) , you may want to buy a second set of wheels at the salvage yard for winter driving. This should take care of the problem.
