Extended Warranty and a Misfire already
So yeah, bought an 2004 Ti Grey M/T with GT package and Navigation(well I'm sure it navigated somewhere at some point), had 30,790 miles then, 31,040 now. Yesterday, I decided that I'd have a little fun on some country roads. After about 10 minutes of easy driving, the fun began... Until I was going up a good size hill, in second, hit 7k and just as I was about to go into third, blinking CEL. So I drove it home, about 5 minutes away and parked it. I have an extended(guess you would call it that) warranty through the non-Mazda dealership I bought the car from and was hoping to get some thoughts as to, do I bring it in, and say "it misfired"? or diagnose the problem (ignition, cat, fuel pump, anyone of the sensors that might be mucked up) myself and bring that issue up to the dealer? or maybe ignore it and say it was a fluke?
Cheers
PS Also even with this issue love the car so far

A blinking CEL is a misfire. There is no doubt of that. I would start testing your ignition system. Check the CAT to see if it's clogged as well. I doubt the "warranty" will cover any of this but hey it's worth a shot. I'd give them a call and see if they will. I doubt it but again you never know. Ignoring this problem could cost you your engine.

Definitely don't ignore it, in fact don't even drive it until this is solved as it could be damaged further. If the ignition coils haven't been changed, do that first. Coils, spark plugs and wires.
Have the cat checked for blockage.
You can choose to go through the non-Mazda dealership, but those generally don't know much about these cars so their warranties come with them trying to figure out how to fix it. You might have to calmly but assertively point them the way.

...darn. Also I can't remember reading it anywhere in the misfire thread or the newbies guide, but will if I hook a scan tool to the obd2 port, will it still give me the corresponding misfire code?

Also, I have a 60 day 3,000 mile through the dealership, the extended warranty, I paid something marginal for through Allstate, is 36 months 36,000 miles and sorry for the delay, its a little cool in CT tonight didn't want to just start the car, grab the codes and turn it off before it warmed up a little.

Also, I don't have a spark tester but my uncle is a professional mechanic, albeit one that has admittedly never worked on a rotary engine before, so I'll most likely try to get him to stop by.

Then either way since your not even certain, you need to replace them ALL. There are a few places you can get everything, local mazda dealer, mazmart and advance auto can get them but they need to be ordered im sure. OR you can upgrade to something like the BHR kit. There are a few other aftermarket "upgrades" with the ignition system but IMO and many others, none compare to BHR's kit.

Easy way to tell if the coils are shot is to pull them out and turn them upside down. If they have a circular white spot on the bottoms, they're bad or going bad.
Mazda has been through a ton of revisions on the coils for the RX-8. I have no idea if they ever got them right... I switched to BHR and stopped having issues with coils, just plugs.

Ajax, It's been tested, debated and proven that the "white spots" dont' mean anything. I've had perfectly good coils with white spots and bad ones as well. I know RIWWP has a lot of links to threads that this was debated.. If i can find them i'll post them up. But you are correct, i too switched to the BHR kit and stopped having problems.

Hrmm..
I still say coils + plugs are probably the culprit.

Yea, And i agree 100% that it's the ignition system. A flashing CEL is ALWAYS a misfire. I would say plugs coils and wires all need to be replaced. Especially since the OP has no clue how old they actually are.

This is only one of them. It's been debated a few times just since i've joined the site. I too once believed that the white spots meant dead coils. After RIWWP schooling me and then doing a lot of research and reading i was incorrect. The white spots dont mean anything.

I believe there's a TSB that says white spots are not a sign of failure.
But back to Love's question
Since you have an extended warranty, and you also have the CEL light on with definite codes, why not take it back to the dealer and cash in on the warranty? You're looking at a couple of hundred dollars (or more) in parts if you do it yourself. Anywhere from $700 to $1500 if you drove into a random Mazda dealer on your own nickel.

But back to Love's question
do I bring it in, and say "it misfired"?.

I've gotten the same thing twice in the 30k/mi I've put on the car, flashing CEL and a noticeable difference in the tone of the engine (much deeper). Coil change should solve your problem... at least it did mine. Still need to figure out why I burn through them so fast, but that's a project for another day.

But you said you read a misfire code. As long as you didn't clear it, that will still be there for the dealer to see.

To give everyone an update. I called up the dealer explained the issue and gave a summery of what you folks have said here and what is in the "Suffering From a Misfire? Start Here" thread and they said to bring it in. Unfortunately the dealership was a hour away but when I got there I looked under the car and the cat wasn't glowing and I was pretty easy on it the whole way there so hopefully the drive didn't impact anything. Also, the salesman had already talked to a mechanic and said that the mechanic had looked up the issue, and he pretty much agreed, so looks like they will be replacing the coils. I'll post anything else they tell me. I just hope they don't put cheap plugs or coils or anything of that sort in the car, we'll see...

They won't be cheap.
Dealerships have been known to charge $1,500 to $1,800 for coils, plugs, and wires. Same stuff you can buy for $200 and change in an hour with a 10mm socket, spark plug socket, screwdriver, ratchet, and ratchet extension, but at least you can be assured that the visit will be anything but cheap.

Hopefully they don't deem the coils a "maintenance item" Warranty companies, including Mazda, have been known to do that.
You will have to ask to see what coil revision they are using, "original", "A", "B" or "C". It's entirely possible that dealerships still have older revision coils.
Other than that, the only way to get inferior to the OEM coils is to buy counterfeits on ebay, so you shouldn't have much to worry about.
