I've got 2 questions i could use yalls help on. I have a 2004 Mazda RX-8 and when i floor it it has a hesitation and takes a second to kick in. What can i do to prevent this. Also what can i do to take off the top speed limiter. Thanks

Make sure to take your 8 into a certified Mazda mechanic as there have been some recalls and tweeks (including a new flash) that are not only available, Mazda is footing the bill! You should also get a free set of plugs installed and your p-train warranty has been extended.

For those of us who want to tune our RX-8's for better performance, how do we obtain an ECM scanner, codes and flasher to monitor and make adjustments to the ECM. Who is the manufacture, and distributor of scanners and flashers that work with the RX-8 like used by Mazda mechanics or performance tuners ??? Thank You in advance for any help or leads one may be able to provide.......

Can anyone tell me wether they have had issues with poor fuel economy and major power loss. RX-8 is an 04 and is at approx. 32k. Dealer hasn't been able to figure it out after 3 trips there and now says its the cat converter, damage caused by me. ?????

Unless you modified the car, it should still be covered under the emissions warranty.

Under Federal law, even if you have modified the car, unless they can prove that your modifications caused the failure, they are legally required to honour the warranty.

For example, if you had a 3rd party tint your windows, and the MAF sensor failed, they can't blame the failure on the window tint. Also, under EPA2, the catalytic convertor is required to be able to last 100K miles. If it didn't, and they can not prove you made a modification that caused the failure, then they have no choice but to replace it under warranty. If they refuse, they are in violation of the Magnuson-Moss Warranty Act.

Right but if you did modifications to the engine or exhaust it would void that Cat-warranty.

Hey everyone, I've had the OBX Headers for my '04 RX-8 for a few months, 'cuz no garage will put them on without instructions. When I ordered mine, they didnt come with instructions. Does anyone know where I can find at least an outline on how to install them? Or can somebody tell me? Pleaseee!!

Hi,

I am new with the RX8 2009 and I need some help to locate the PCV Valve hose to install a product that will give 10 HP more and save fuel by 22% and more. Can someone help with that issue?
