I purchased a 2005 RX-8, 6 speed (I think, its missing the shift pattern sticker but i had to push it down and far right for reverse) it has 103k miles.
The couple I bought it from purchased it at an auction just about 2 weeks ago (sketchy, I know) So they have no idea about its history.
The test drive went well. No Check Engine lights were present. It still pulls pretty hard. Idled it for about 20 minutes with no issues, oil levels were a little above halfway, temps stayed below midrange.
BUT when drove it home on the freeway there was a flashing exclaimation mark. I immediately went to autozone to use their reader.
Starting my car back up 5 minutes later (after arriving at autozone) there was no exclamation mark, but the reader show a code of:
P2259- "Secondary Air Injection System Control ?B? Circuit Low"
^ I have no clue what this means ^
A few good things I noticed about the car is that it looks like it has that AccessPort Cable coming from the dash, so it looks like the previous owner had an AccessPort. Most likely a good thing?!?
The other thing is that after parked and shut off my car at autozone. I went inside for about 5 minutes. Came out to my car to hookup the reader and I could hear fans running (Car was off) thats a good thing... right? Lol, but is that a factory setting?
Sorry for the convoluted post but could you guys shoot me links to premix, where/what to buy and ratio.
I want to only get this machine caught up on maintenance, then make it more reliable if thats even possible. Im not interested in making more power
Secondary air injector is an emission device that pumps air to the cat when the car is cold. You need to see if the fuse is blown or the pump itself is shot.
Car will turn the fan on when the car is off.
As for Premix, I use Idemitsu but you can use any 2-stroke oil that's JASO FC or ISO rated. Normally we go with 1/2 ounce per gallon of gas.
The stickers are from the dealership that performed recall/TSB work. Many dealerships fail to affix them, but they are part of procedure when work is done under the campaigns. You can likely cross-reference the dealership code to find the servicing dealer, they may have more records on the car. Mazda, doesn't usually keep national records of service work (except recalls), but the individual dealers that worked on the car will have records to indicate what was done and when, you just have to guess what dealer(s) would have worked on it.
Campaign No - Description of recall
0516J – Fuel Pump Sealing Rings May Leak Fuel – 2004-2008 Mazda RX-8
8215F – Driver Air Bag Inflator – 2003-2008 Mazda
P2259 refers to the solenoid that controls the vacuum-actuated valve for the secondary air injection pump (emissions device that runs on cold start). Click that link for info and troubleshooting steps. The solenoid itself is mounted next to two others on the back side of the upper intake manifold (between manifold and firewall). It's possible that it's a wiring or connector problem but my money is on the solenoid.
Odds are, it's failed. You can find them for under $20 on Amazon, $100+ from a dealer or $50-$70 from RockAuto. I've purchased two from Amazon and one is still working while the other was bad on arrival (didn't hold vacuum). The part number is KL0118741.
The flashing exclamation mark, if it's red, is your brakes. If it's orange, that sounds more like the tire pressure monitoring system. If it's the check engine light flashing, stop driving immediately and examine/replace the ignition coils, spark plugs and wires and/or catalytic converter (depending on its condition).
You're taking a risk buying a 100k mile rotary with unknown history, but Mazda should be able to give you some history given the VIN. Like if the engine has been replaced. Usually we recommend having the engine compression tested before purchase.
Read the owners manual and see what light it was that came on. It sounds like the tire presser was the light that was going off, It's off when the car is first started and then it come's on after about 5-10 min of driving for me.

Thanks for the detailed post!
Im going to checkout those solinoids today. What exactly do they affect though? Could their failing cause an overheat?
The car has been running amazingly regardless
I just came back from my local Mazda service center to get my last recall (1017E) performed. Those stickers were for the the other recalls. So I'm all caught up on those.
FORTUNATELY, I live about 1 mile away from Lucky 7 Racing here in Duarte, CA. They ran a compression test and the numbers werent too great [Ill post later] but it was estimated that I have quite some time before a rebuild is needed, provided I keep the car in proper order. They also replaced my ignition coils and wires last week (the plugs were pretty new) and the car has been running like a freaking champ. They also advised I buy the mod to start running the cooling fans at a lower temperature and an upgraded starter. Im going to check which starter I have today and go from there.
Im going to post some pictures later of some aftermarket parts the car has. I need direction in whether to keep them or go back to OEM.
I know for sure it has Mazdaspeed shocks with RacingBeat springs all the way around. However the car feels really bouncy and even though its not really low, I can hear something hitting coming out of driveways and dips. Maybe they need a rebuild?
