This is Rev hang. It releases less emissions than a standard manual gearshift. Modern car manufacturers have strict emissions guidelines to meet and in a manual transmission the ECU has less control of the engine and thus less control of emissions released. Keeping the throttle open after a gear change allows airflow to the engine to combust all remaining ...

13.86 volts when the car is running means your alternator is doing its job. You can recharge the battery using a charger, this is more effective than having it charged by your alternator with the engine running. Once it has a good full charge (reading at around 12.6-12.8 volts) you can do a load test to see if it is bad. Most auto parts stores or places that ...

NOTE: You state "piston bearings" ... which don't exist. I'm assuming you actually mean either the rod or main bearings which the crankshaft rides on, so that's what I'm going with. Technically I suppose you could ... but why? It doesn't make sense for many reasons: When you get new bearings, they come as a set for all of the journals. You've got ...

It is my understanding the LF-VD engine in your Mazda 3 is an interference motor, meaning if it actually did break the timing chain, you will most likely have incurred damage to the engine. With that said ... Before you start thinking it's the timing chain (worst case scenario, IMHO), you should check the "other" things which might be happening with the ...

After much searching high and low I found this youtube video that solved my issue. In a nutshell: It seems that trying to pair with the default pin (0000) does not work. You need to set a different pin by pushing the numbered buttons on your console (mine look different to the video, but they work the same). I set a pin of 1111 by pushing the buttons 1 ...

Throttle body needs a serious cleaning. Gunk or some sort of residue is sticking your throttle at 3000 revs. Disconnect the rubber intake tube assembly and use a good quantity of throttle body cleaner and a couple of squirts of wd-40 to ensure the throttle mechanism itself is free and operating normally. Your vehicle being 2001 vintage I assume that it is ...

I ended up buying a new clutch assembly and installing it as my first serious attempt to solve the problem. The thermal sensor is located on the other side of the compressor and there is no way to replace it without removing the compressor, which you can't remove without having the refrigerant professionally evacuated at a shop. So, I spliced the wires from ...

There's a metal cable that connects the climate control unit to whatever it is that directs the air flow. The cable could be seen underneath the dash directly (on the driver's side, near the center vents), and pulls on an air redirection mechanism (blend door? or something like it) in the same way a brake cable does on a bike. For whatever reason, the ...

If the dealer has measured them, even though most of the corrosion has now gone, they may be too thin and need replacing. Given rotors are cheaper than the consequences of brakes failing, I would put the news ones on. And have just done so on all 4 corners of my car.
