same story for my 04 RX8. Heat shield fell off last year, and now I have oil leaking from oil cooling system. Dealer says I need a new oil cooler and all lines. Will look at it myself when I get a chance this week. Meanwhile leaking about a quart every 150 miles.

Same story here in NJ with 2004 RX-8 with 51,000 miles. I am the first and only owner of this 8. Hot air blowing when AC is turned on. Happened two days in a row. First day it was fixed by twiddling the temp dial. No luck second day. It is in shop now for replacement - quoted cost is $650!!!! Looking to get that back when Mazda acknowledges the problem in their first year production models.

#123 of 129 performance chips by thecat1

hi i just purchased a 2004 gt with 17k. it hasnt seen a winter and was garage stored all the time. it is beautiful. In reading these forums i am suddenly afraid that the engine wont last as long as i planned. Anyway has anyone tried these performance chips out there. they claim to really boost hp and milaege as well. the gforce chip for $69 seems too good to be true. they also claim that it does not void warrantys because it just clips on somehow and doesnt alter the original equipment. look forward to hearing from someone...

All chips are a scam. Simple. Just a scam.
 
Custom re-tuning or otherwise, is a different story.

#125 of 129 Wheelbearings or rearend noise by bullwinkle fan

My 04 RX8 with 58k seams to have a louder road noise ( rumble ) now than before. Had tires rotated and balanced last week but didn't help. Anyone have issues with wheelbearings or rear end noise ?

"Once warmed up I'll keep the revs up, never going below 4K and usually between 5K and 8K. The best way to destroy a rotary is to lug it. Rotaries live to rev -- it's what the engine was designed for."
  
I was just reading through, trying to get any tips on taking care of my RX8 when I came across this. I'm 17 and bought an 06 rx8 last November. I parked the car through the winter to avoid rust and everything else and brought it out around March. Before Winter I drove it several times, glad to have a fast sweet ride to care for and work on. I drove it hard and fast and it ran like a champ. The following Spring i brought it out of the garage and drove it daily.. I've put about 10k on since then.
 
Over time it seems like the engine has been slowly losing power. I drove it hard, like it should be, for the first few months but then dumb judgement came to me and a began to cruise at about 3k rpms for fuel mileage. i know rotarys are one of a kind, but i never thought it'd hurt.. needless to say i was pretty p/od when i realized it didn't respond like it used to. i looked into the problem recently and figured it could be bad plugs, so i replaced them and it helped but not significantly.
 
Not to add ignorance to this or the stupid teenager stereotype but i raced an AT 90 something camaro with a 350'. Smoked it, noted ending at 135 mph in just a mile. recently i raced an 04 chevy impala. i lost, feeling clueless as to what the h*** couldve happened. also, one late night after changing plugs, i took it for a cruise, taking about 2 1/2 miles to reach 135.
 
Anyway after writing a novel and reading your comment, im frustrated with myself and sure that driving low rpms is the cause of my lack of power. I'm not searching for the power to race idiot drivers, i just want the power that i know belongs there. I called Mazda a few months back, wondering if they could diagnose a problem. My check engine light isn't on and apparently they can't give a diagnosis to an unknown problem without the light being on itself.
 
I'm sure you weren't prepared to give me a full diagnosis but i figured you might know what could be done to get this one of a kind car running again. If you have any info or just tips, I'd probably be the happiest kid in the world. Thanks a ton,
 
Wes

Please keep your service & maintenace paperwork. Ensure that the compression is alway within tolerance, if it is low or you start to have problems with repeat trips to service, make sure they tell you exactly what is wrong and how they are going to fix it. But enjoy it, it is a nice ride....
