I was driving to work today and noticed a bit of smoke out of the back of my car on the highway, which was pretty unusual but stopped after I was cruising. About 10 minutes later I tried redlining it in 1st from a stoplight.
At around 6-7k RPM the power dropped off instantly to the point where it jerked me forward in my seat. I looked out the back window and had a decent cloud of black smoke coming out of, as well as into the car.
I tried reproducing the issue on the way home and had no luck. Compression came in around 7.5 about 2 months ago with no large variation between faces or rotors. Which was largely the same as it was a year ago.
To me this sounds like the APV not opening correctly or an ignition issue of some kind. Are there any other common causes for something like this that I should look in to while I've got it on a lift tomorrow? Could a bad O2 sensor cause such a drastic power loss?

Avoid driving the car for now. You might end up destroying the cat.

I recently traded my truck for a 2004 Mazda RX8. I don't know if this is a dumb question or not , but when I put the car in reverse, back out and put it in drive the car jerks forward and drives normally after that. The guy who owned it before me said he had bigger tires on the back, but I don't know if that could be a reason for the rough shift because I don't know much about cars.

Also, not sure if you are doing it, but don't change direction without stopping. Back your car out, stop it completely, then put it in D. Same thing the other way, stop completely before you put it in R. Applies to all transmissions out there. At least on an AT, there is no nasty grinding if you put it in R when you are still moving forward.
I highly suggest you read the New Owner sticky before something goes wrong for you.

Air inlet duct elbow
Anybody have any tips on how to remove the air inlet duct elbow from the accordion tube? Having some trouble. The elbow split in half from the hose and now it’s stuck in the socket. Luckily, got the half that was stuck in the hose out.
Thanks

Are you talking about one of the three breather hoses just in front of the throttle body?
If so, what Kamal El says. You just have to carefully dig it out.
If not, I have no idea what you're talking about.

You should be able to get behind it with a flat blade and wiggle it out. Like others have said, use some spray lubricant to aid removal. You can get the appropriate size 90' fittings at a hardware store instead of ordering new from dealership. I found nice black plastic barbed fittings at a local do it best center.
Be sure to not drive the car without those hooked up. One of the vacuum hoses plays a crucial role in the operation of your oil injectors.

Technically you are not even supposed to tow start modern manual cars. Maybe in a pinch, yeah, but it's not supposed to happen on a regular basis.

I saw somewhere that the trim piece with the aux input, in the center console of the S2 can be replaced with a similar piece from a Mazda 5, which will have a USB port instead (I think).
Does that ring a bell for anyone? I can't find the thread anymore.

Okay, Air conditioning control ***** -
,
!
Look, I don't care what it looks like at this point, can anyone show me one for around $10-15 that will WORK? The inside portion of mine was apparently brittle plastic that just snapped. And now I have to change my AC controls with a pair of pliers I keep in the glove box.
