Does putting an automatic car into neutral at stop lights significantly harm the transmission?

It could be argued that by putting the car in Park or Neutral, you are saving wear on the torque converter, which can be an expensive piece of equipment to replace. But I can't site any first-hand ...

MAZDA 3 2006 (UK) - poor acceleration then takes off at 3250 revs

My gut says it's likely to related to either a dodgy throttle position sensor or a faulty air mass meter. Whilst it is reporting no errors, it's worth doing diagnosis such as resetting the throttle ...

Timing chain jumped. Probably bent a piston. Is my engine worth fixing?

IIRC on the 2.3 there is no keyway to keep the crank gear and balancer aligned. If the engine is spinning and has compression you probably spun the balancer and it's out of time. Set piston 1 at TDC ...

How can you tell if the engine is not brand new?

It definitely sounds like you have been ripped off. It honestly sounds like the old mechanic is up to no good. You can search the VIN which is stamped on a metal plate on the engine to make sure it ...

What is the funny looking thing attached to my new mazda3 key fob?

That is a dealer ID tag. The salesman and managers use it to check keys in and out. They should have taken it off of the key before they handed it to you. If you don't want it, just take it off and ...

Timing chain jumped. Probably bent a piston. Is my engine worth fixing?

I don't see how the timing chain could have jumped or broken in this situation. If the wrench was on the crank pully, and this is what stopped the engine, there was little to no force on the timing ...

Is this Mazda 3 motor mount broken?

Whoever said that these mounts commonly fail is entirely correct. These mounts are oil filled. The brown stuff on top is likely not hydraulic fluid. When the mounts fail they split along the bottom ...

2012 Mazda3 shifts gears but won't move

If you can depress the pedal and select gears with the engine running, but then don't have any drive once you have selected a gear, then I'm afraid it sounds very much like the clutch has gone. It's ...

How can you tell if the engine is not brand new?
