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!

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)

When you turn the key and you hear a clicking sound more than likely the battery is dead, try charging or replace the battery. But if everything works like the head lights and radio and you still hear the clicking sound then (it's possibly the starter?) (NOTE: If your gonna replace the battery you will have to take the car to a mechanic so they could re flash the computer.)

my name is Gary and i am about to purchase a used '04 RX8. i am getting scared though of all these customer reviews with all these horror stories about flooding engines and broken this and broken that and A/C not keeping the cabin cool enough. I just read your post about how you have to keep the car above 4000rpm most of the time. So, does this mean I have to drive the car fast all the time or can i just drive in lower gears? Because if I start getting a lot of speeding tickets my wife will kill me. LOL.
I only work 7 miles from home and it isn't a "fast" road. so i can't speed on it, plus cops are always patrolling the road. Any suggestions as to what i should do? I really want this car but I don't want it in the shop all the time like all these other idiots! LOL
So, again, would it be ok to ride it in lower gears for that higher RPM?
Also, is it true...you shouldn't turn the car on and then turn it right back off? you should let it warm up a bit? what about winters? is it hard to start if it has been sitting in my parking lot at work for 3-4 hours in 25 degree weather?
thank you for ANY advice you can give me!
if you want, you can email me at gsteinberghotmail.com with anything you have to offer for advice. i want to keep this car pristine!
