Have you had any problems with your RX8 coils? Did Mazda
 give you a new engine? If not I would check your coils
 or have the dealer take a look. Mine look like this
 and I assume they are getting ready to fail so I bought
 a new set. My check engine light did not come on yet.

 RX8 coil failure means instant engine failure
 if the check engine light comes on and you do not stop
 right where you are. Do not drive the car. Have it towed
 to the dealer. An alternative to this is use a Car Chip
 and carry a Windows note book computer in the trunk.
 If the check engine light comes on stop the car
 and read the CarChip. If the CarChip says engine
 misfire you have a coil problem and get the car towed
 to be fixed with new coils.

 This would be a biz  opportunity for a computer programmer
 and designer to get wealthy. Build a device that mounts
 on the dash board that monitors the OBD II connector
 and reads out the fault codes in plain English in real time.

 I can see lots of other uses like monitoring the mixture
 ratio in real time to get the best MPG.

 It is also an opportunity for car manufacturers to offer
 this feature as an option. Got a suggestion box C Smith?

Paul...

I also get close to 100 emails per day...often more. Counting the
ads, and the notices that say I've got 100 million dollars
waiting for me in Nigeria! <G

No to both...Mazda did check out my engine during that recall,
but decided I didn't need one.

I bought an OBD II reader from Harbor Freight

when it was on sale for $49. I did get a check engine light on
the RX8 last summer, and it turned out it was the rear O2
sensor.  I replaced it with a "generic" one.  The generic was a
Bosch, and came without a plug on it...guess that's what made it
generic.  Mounted the plug from the old Mazda sensor on the new
one... cost less than $50 from Rock Auto and an hour crawling
under the car.

Been meaning to ask...could the oil in the gas have caused that
rear sensor to fail?  Or can I expect them to die around 60,000
miles?

Could be the oil in the gas. How much are you adding?
Is it 2 cycle oil? What brand?

I have been adding a 1/2 oz per gallon. It just went through
CA smog check with flying colors. 30,000 miles.

If I were you I would take off the intake system and
unbolt the coils  and replace them with Pep Boys versions
as soon as possible. I assume the Pep Boys versions are
the updated type as they do not have replacements for
the 2004. I'll let you know more in a few days.

When you get them off and they are discolored you got it
just in time.


That OBD II monitor was exactly what I had in mind.
The Chinese beat us to it.

I'm using Wal Mart's 2 cycle...Super Tech TCW3...have been since
my RX7...1/2 ounce per gallon...I use a graduated clear plastic
funnel I also bought from Wal Mart. It has a valve on it as well
so you can start and stop the flow into the gas tank.

My annual emissions inspections have been good here as well.
Although the O2 sensor would have failed it if I hadn't replaced
it last year just before inspection time.

Good time for me to check and/or replace my coils (I assume you
mean the ignition coils?).  A friend of mine is visiting her
daughter in Phoenix, so I have her Tucson to run around in the
snow with!
