Yea O2 sensors were also changed, twice if I remember correctly. It's just insane that Mazda's only answer when all the changes do not work, is to change out the engine. That's fine if your under warranty, but who is going to pay for an engine swap, when there should be a reasonable fix. Crazy.

Try changing the air filter. Mazda uses platinum spark plugs. replace them with (NGK laser iridium spark plugs) this should solve your problem. if the car still don't start check the fuel pump fuse! Open the hood to the right of the air filter is the fuse box there are two blue fuses on the bottom it's the one to the right.

I've sold several over the years, and it seems to be that the harder they're run, the btter the rotary motor does. They are certainly very sensitive, anyone remember MG, triumph, etc?? They need to be warmed fully when run, good gas is a must, and the rotary is a high RPM motor by design, the harder I've run mine, the better they've been. And I"m with the prior post, 3000+ RPM seems to help too

You might have to replace the IAC motor ( idle air control = DEALER ITEM) that's what keeps the idle steady when your stopped. After about 60.000 miles it starts to fail, also replace the coils and spark plugs. All that might cost you about $1200 at the dealer!

Drive It Like You Stole It For 200K Miles Plus by ksmigel

If you go over to the rx-8 owners club forums, you'll see that many people have 100k, 150k and even 200k on their rx-8s (that's a lot of miles for three and four yer old cars), with few or no problems.
 
The common element: They all bought manuals, and drive them hard and fast, the way the rotary was meant to be utilized.
 
The best thing you can do to a rotary is redline it. The worst thing you can do is lug it. If you're spending most of your time above 4000 RPM, your 8 will thank you.
 
Make sure you redline it a couple times a day.

I have just purchased a used 2004 Mazda RX-8 with 88,000 miles. I am having an issue where, while driving the car the check engine light and the TCS/DSC Indicator light will come on. When it does the the car will stall - mind you this is while driving down the freeway doing 60+.
Can you help me trouble shoot this?

Drove it to my nearest Mazda dealer to have checked.
Throttle Control valve and gasket needs to be replaced. ($436 just for the parts)
