That's still my favorite generation of BMW M3. To be fair to Mazda though, there are some things that have to be considered when comparing these numbers. That was a fairly exotic engine design in it's day, more expensive to make and far more expensive to fix than the upcoming Mazda engine is...

That's a very good theory, and one I agree with it. I'm disappointed in myself for not realizing this. The Skyactiv 2.5G even has harmonic resonance sensors in addition to the normal knock sensors which makes it even more likely. They were added to detect LSPI (low speed pre-ignition) which...

In fairness I wouldn't call it common, but we always get a couple of weeks every winter where it is that bad. Sometimes worse. The windchills are genuinely dangerous around here during those times. It's hard on people and machines. A lot of the discussion between members has been of temps in...

Yeah, I acknowledge that I look narrow-minded about it when viewed from the other side of the fence. There is more to this whole thing that I didn't go into because it's off-topic mostly. My experience with the dealership was, to put it bluntly, horrible and I just didn't want to deal with...

My CX-5 was a 2017, prior to the introduction of the cylinder deactivation feature. I arrived at my conclusions after considering all the evidence and my first hand experience. The vehicle was throwing no codes, and there were no stored codes when I checked with a reader. To me it simply...

Two things: this behavior happens in the naturally aspirated version of this engine too, and the power loss in the worst case scenario is so severe that it calls into question the safety and driveability of the car. Feel free to accuse me of exaggerating if you want, but unless you own one of...

Going back to an older car is really interesting when it comes to things like this. The trend for all new cars is stiff suspensions and hard as a rock seats it seems. As soon as you jump into some old thing from the 90's the first thing that strikes you is how you sink into the seat cushion...

High humidity might affect the turbo too. The Ford Ecoboost engines are kind of infamous for having instances of cutting out or stumbling after running at highway speeds in the rain. Apparently condensation in just the right place near some sensors will fool the engine into thinking it is in a...

It took 3 weeks before my hips started aching after I bought my '17. Nerve pain is weird like that. The effect was cumulative and continued to worsen with time. The side bolster was pinching my sciatic nerve into the side of my hip bone. Kind of just bad luck on my part really, I don't...

I didn't mean to imply that oil temp was the only culprit here. I mentioned air intake sensors before and it's very likely that the computer is dynamically adjusting engine condition based on a whole range of sensor inputs including oil temp, air intake temp, static pressure and humidity, and...

Two thoughts to share for those whose theory is that this behavior is intended as a traction limiting measure: 1) The behavior is progressive with temperature. Many of you have never experienced this at severe temps such as -10F or -20F. I have. At these temps the vehicle feels broken...

They key reason for moving to more speeds is to get a higher overall ratio spread. This directly impacts fuel economy. Mazda used to match or beat some other makers by massaging their designs in other areas such as taking as much friction as possible out of the engine and drivetrain, but the...

Bring back the 2-door while you're at it Mazda...... Yeah, I know, there is a zero precent chance of that happening, but a guy can dream. I always really liked the hatchback coupe Mazda 6 from a couple of generations back that never came to North America. Was always hoping it would but even...

The critical sensors are usually in the thermostat housing and at the engine intake, not the air filter box. You wouldn't want them to misreport anyway, all it would do is make your engine run poorly in ways worse than what's been discussed here.

There are sensors at the engine's air intake that measure air density and temperature. The ECU needs this information to help set fuel/air ratio mixes, set spark advance/timing, etc. It doesn't rely on the temp sensor that displays ambient temperatures to the driver, that information is not...

I've been suggesting all along that the root cause of this behavior is timing retardation based on MAF readings. It's just an overly aggresive protection mechanism for the engine. Higher air density means you can get a lean condition unless it is compensated for, which is important to prevent...

I'm not going to add much here because I was shouted out of the room the last time I tried to participate. I just want to note that at the temperatures you guys are discussing the power loss condition is mild at best. You should experience it when it's -20F like I did. The issue is SEVERE at...

This is by far the most likely scenario. If they had to disconnect any lines during the tranny replacement and didn't properly bleed the air out of the system then what happens is the air bubble gets "stuck" at the heater core inlet. Sometimes you can temporarily clear it by taking a couple of...

You're right on the mark here. Most people don't know much about the science behind light. These LED lamps put out a lot of lumens, but the fidelity of that light is often poor due to limited spectrum coverage just like you said. The end result is lots of light but still not being able to...

Not sure if you're trolling or just venting.... if the latter you must realize the kind of reception you'll get on a forum dedicated to Mazda enthusiasm. If nothing else posts like these help me realize I'm not as picky and anal as I think I am sometimes. If you're seriously stressing about...
