A simple test that you can perform in your own driveway is: For each corner of the car, push down hard several times (the car should be bouncing visibly up and down) When pushed down, release and watch The car should bounce upwards (above the normal resting point) and then immediately settle at the resting point. Additional bouncing indicates worn or ...

Apparently, this is the Mazda limp home mode. If you check that link, two common causes are: Vacuum leaks Bad ABV solenoids In discussing with your mechanic, I would suggest first having them scan for codes to see what is triggering the limp mode.

They really are that simple - as long as you torque them correctly, there isn't a lot that can go wrong. They are designed to be as straightforward as possible - they don't require calibration, measurement etc. Make sure the connector is securely on the top of the spark plug, and make sure you don't get oil or grease on the contacts. And do them one at a ...

The question is can I just go out and buy any 17mm bolt that is the same length as the current one, No. or is there some kind of material requirement? Yes. Think about the jobs that those bolts are doing: they support the steady state mass of the vehicle and the transient spring loads of the transmission. That means that those bolts need to ...

I think you threw a wheel weight. Let's consider this quote from the great Wikipedia: When the wheel rotates, asymmetries of mass may cause it to hop or wobble, which can cause ride disturbances, usually vertical and lateral vibrations. It can also result in a wobbling of the steering wheel or of the entire vehicle. The ride disturbance, due to ...

Unfortunately wheels will get dirty first - they are closest to the ground so will pick up everything; they also pick up brake dust, which is very sticky. This means there is no silver bullet here - you need to wash frequently, and apply a wax if you want to slow down the build up of crud. Use a wheel cleaner solution to dissolve the worst grime and combat ...

It sounds to me like a dead battery. Depending on how accurate your voltmeter is, what you see as 12V may be 11.9V or lower. To give you an idea, an open circuit battery terminal voltage of 11.7V indicates a completely uncharged battery. What you are describing happened to me once with a Volvo car, due to a faulty switch in the glove-box; the glove-box ...

Unfortunately, there are many, many things that can cause a rough idle. I'll try to cover a few things that might help with the diagnosis. I'm sure that there are many others that could be added. Like I mentioned in my comment, it's definitely not the fuel filter. If a fuel filter was bad enough to affect idle it would stall instead of accelerate. A ...

The first major symptom that appears when spark plug gaps get too big (from wear) is that you get a band of hesitation only at full throttle and somewhere well below peak torque. This is the band where the most voltage is required for a successful spark, because at this time mixture is most dense. Below this band the mixture is less dense because less ...

First off I can say that I have done something like this, but with the ignition and not the horn - my friends ignition switch broke so we wired a bright red push button directly from the battery (well - actually a fused 12v line inside the car) to the starter motor coil - it has since worked like a champ for nearly two years. First off - DO NOT wire ...

If you have checked another working window, your best bet is to use a multimeter to see which wire carries what voltage for the up and down signals (this is not specific to your cart but relevant for any). Then check first to see whether the voltage is present at the motor end of the wire. If so, the connection to the motor may be faulty. If no voltage ...

Based on your wiring diagram, the relay is inside the switch, and based on that it's not serviceable. Based on the picture you posted here That black square box on the switch (tyco) is the relay. Here is are the specs (PDF) Here is a where you can buy it Based on that I would say it's replaceable, with some soldering required. It would take some ...

I like to put a little anti-seize on the threads before putting the new plugs in. That helps ensure the plugs come out nice and easy the next time you have to do it. It doesn't need very much and make sure not to get any of it on the electrodes.

The firewall is typically made up of metal with a layer of fire retardant material. There are holes through the firewall for necessary pipes, wires etc from the engine bay to the passenger compartment. With old cars (much older than a Mazda 323) I have seen heavily rusted firewalls, but not seen anything like that recently. It certainly shouldn't be a ...

You should do a load test on your battery and see if you have a damaged cell. If this is not the case, check for a parasitic draw test on your vehicle, which basically tells you if something is on and draining your battery.

I found the following on the iKeyless website, which indicates that you cannot program the key yourself and would need the dealer or a locksmith to do it. Key Cutting/Programming: Programming instructions are not included. This device requires cutting and programming by a dealership or locksmith. The procedure takes only a few seconds to complete ...

Sounds to me like the technician didn't burnish (or seat) the brake pads. Anytime you replace the brakes pads you should make several hard stops (not enough to activate the ABS) from 35 and then 55 mph. This seats the pads to the rotors, and eliminates the spongy feeling.

This should be safe logically and based on personal experience. Most cruise control systems use engine vacuum to pull on the throttle cable and the vacuum is always there when the engine is on anyways, so there is nothing mechanical running behind your system switch. 2012 Mazda 3's have either electronic throttles or cable. The cruise control system with ...

You should never mess with the safety systems, ever. How tall is your GF? If she's short enough (I believe under 5') the air bag could be dangerous, given that it will hit her at an unsafe position. Given that, it may be better that the airbag is in fact off. Supposing she's of average height, you've only got two real next steps. Push the dealer harder, ...

Her weight doesn't really have much to do with the necessity of an airbag- I'd say it'll still be a massive improvement in the safety for the passenger if it goes off for a light passenger. I would also strongly recommend against trying to modify the airbag sensors yourself, as you might cause a lot more problems that you'd solve that way. Which IMHO ...

A 2005 car will be OBD-II so with an OBD-II dongle and some appropriate software you should be able to read the basic information you get via standard OBD-II. Depending on how Mazda implemented the connection you might well have to use Mazda-specific software to read all the information that the ECU can provide.

As Tim suggests, clearing the code doesn't solve the problem if it's not a random positive. The engine temperature gauge is fine Based on the information that you've provided so far (and using Tim's link as a reference), it seems likely that you have either a bad engine coolant temperature sensor. The implication from your PS is that the car is, in ...

I can't speak to the Torque app, but in my experience the US Gov ratings are typically quite a bit lower than what you can expect to get in actual normal driving (Gov ratings seem to be based around someone that does 15mph+ over the speed limit all the time, launches from every stop light, does full-throttle passing, and doesn't see red lights until they ...

That rev range does sound high. It's sounds like the transmission is trying to shift to overdrive (the highest drive gear) but isn't succeeding (scary jerk but no change in speed). Some internet research indicates that the CD4E transmission in the automatic 626s from that era could have potential problems. However, reading further, I begin to wonder if ...

This sounds to me like a sensor problem. Most modern engines vary the air-to-fuel ratio automatically based on the engine temperature, and do other complicated tricks like changing the spark timing based on temperature and other factors. If one of your sensors is giving inaccurate readings, especially the coolant temperature sensor, all sorts of things could ...

If you were to simply replace the existing petrol engine with an electric motor, then yes, it would ruin the gearbox very quickly, as it won't be able to handle that amount of torque. However, even if the transmission would cope, that wouldn't be the best way of doing it - an electric motor has a very different torque curve to an internal combustion engine, ...

After much Googling and trying to interpret vague descriptions on internet forums, I have discovered that this is apparently the ambient temperature sensor, used to display the outside temperature on the center console. It is normally mounted in front of the radiator, in the center-ish of the front grill with a plastic clip. Unless someone has some ...

The noise you are describing is likely the wear indicators on the brakes. They are small metal tabs that come in contact with the rotor when the pads nearly gone. It's designed to let you know that your brakes need to be changed. You mention that you just replaced your brakes, did you do all four wheels? It might be the lack of shims, or disc brake quite on ...

I've had very similar sounds from a bad wheel bearing before. For a 2008, that would be an early failure though. Not likely, but if you rule out the other items, check the wheel bearing play/feel.

Most likely case is a bad throttle position sensor or a bad air sensor (some cars use mass air flow, some use manifold pressure). This is typically not something that can be seen in codes, but must be identified by comparing sensor data and graphs. Other possibilities could be a vacuum leak, but that would probably throw a code/check engine light. Of ...
