I am about to turn 50k. Around 30k, my car started acting up. Big power loss when driving over an hour a day. I am talking about major power loss. Fans would run for 30 minutes after shutdown. My cup holders were cup warmers. My truck was a toaster oven. I am aware that rotaries have fought heat from birth. No CEL either. There are a bunch of threads that have the same issue. I can almost bet your CAT is gone.

Getting rid of the car has or never will be my option, unless its is wrecked. Contacted Mazda North America several times, which I recomend. Took the car to Memphis dealerships and Jackson dealership. The dealers have not a clue. Told me to bring it by when it was acting up. Did that. Nothing. I started feeling like I was crazy. Maybe its something I have done? No.

New intake, new plug wires, new clutch, new pressure plate, new flywheel, new plugs, reflashes to CPU, different gas. and repeated resets to both memory banks.

As hard as I tried, the more it became more of an issue. For starters, my gas mileage was dropping to 180-200 miles a tank. All these parts I am throwing on are physicaly more effecient than a stock 8.

The dealer at one point ruled out the CAT. This is after telling them I heard a leak from exhaust somewhere. Nothing.

About a week ago, I jacked my car up high enough to take a gander at the exhaust system. Did you know the CAT is the lowest point in ride height? Did you know the parts inside the CAT are very delicate? There was some battle damage. I ordered a midpipe that moment. This was the only thing left before giving up on the hunt.

Son. Not only did I solve the problem, but I got a bad ass car. This thing will freakin move man. No CEL after 600 miles.

When you shake the CAT, you can hear bits and pieces inside. It is a two stage CAT. The sensor is between the two. If the Aft section goes, no CEL. Mazda will not address this. So I had to take it in my own hands.

Its hard to say what kind of gas mileage the car gets. It just wants to tumble those rotars. I am getting way better than I ever have. I bet she could go to 275-300 a tank.

Try cleaning your MAF sensor first. Run some octane boost. If that does not solve it. I would really consider looking at your CAT.

1. My Engine Light Came On And I Had No Power Above Mid Rpms.

2. Took My Car To The Dealer And They Called Me Telling Me It Was My Intake And That Carbon Deposits Were Interfering With The Butterfly In The Intake Not Allowing It To Open, Setting Off The Engine Light. They Said If The Intake Doesnt Open Completely Above 4800 Rpms Then The Light Would Come On.
I Asked If It Could Be Cleaned And He Said You Can Take A Injector Out And Try To Clean It But It Most Likely It Will Not Reach The Area Due To Where It Is And Probaly Wont Help For Long.

3. They Said The Tech Support Said They Had This Occur With Rx8's With Higher Mileage Still In Warranty.

4. I Called A Mazda Rep And Explained The Problem , Then They Called The Same Service Manager And Told Him To Call His District Supervisor To See If He Would Help With The Cost.

5. Who Wants To Pay 3200. Every 50,000 Miles To Keep A Car Running Well. I Could Unerstand If It Was A Clutch Or Something That Is Supposed To Wear.

Sorry This Is So Long, Anyone Have This Problem Or Ideas, Now Im Thinking Of Buying A Mustang Because Of The Several Problems I Have Had In The Past Also. Thanks Roger

what i mean is i turned the a/c to HOT and turned the fan level to 3.
this rattle only occurs at certain temperature, when the ambient temperature is cold, it's perfectly fine. somehow it rattles only at around 15-26 degrees C.

No, it rattles when i hit into a bump

I have an automatic with the tiptronic....
So I bring it in to be checked....and sure enough, a new transmission was ordered and installed....
The loud rattling noise is back, but i doubt it's the transmission....it sounds like I am dragging coke cans....any help or suggestions would be appreciated!!! :tear:

Other than that I haven't had any problems with my car except for the collapsed motor mounts--which they replaced in about an hour last Friday.
