RX-8 Flamed blow out - Any ideas?
 

Well here is the story i was coming from wedding rehearsal and getting ready to meet up with my folks for dinner, thought i would stop by the auto-wash (being lazy) and have the car looking super clean for papadeux, anyway i got out the auto-wash and the car started to hesistate and putter halfway down the service road i was unable to go over 40mph. So i pulled over and the car dies and the check engine light is flashing , hell i figure water got in the engine some how or the intake so i inspect everything and nothing checked the filter (bone dry) , what else could it be. So i waited a little while and and it cranked back up no issues ate then drove home got about 20 mins along and the same issue this time i saw sh!t flying out the back so i pulled over and there was this:

So i figured at this point the cat is gone even though the glow looks nice , had the code checked out and it said fould spark plug , im like ok ill buy that so i bought new plugs wires and spent saturday changing them out. Sweet now that im done and its darks reset the ECu light stayed on F-it , lets go ride, so my boy grabs his camera and we get about 30 mins out - no issues - go eat come back home and it started all over again so my boy notices something coming out the exhaust so he grabs the camera and this is what we got;

Now im screwed till i can get it to the dealer , mind you in the upside down vid i was only doing about 43mph trying to make it home cause we were on a bad road to get stuck on , felt like i was only running off one rotor.
Any ideas till i get it to the dealer ?

*waiting for the no0b to ask how he can get his car to do that*

D0o0D h0w c4n i g3t My caR 2 d0 dAt hahaha
sucks. at least you got it taken care of and felt kinda cool for a little while haha

LAWLZ

whatever it is I am sure you need a new Cat now

Yep, looks like the cat is gone. But, you have another problem also. There is a lot of unburned fuel in the exhaust causing the flame. Check plugs and coils.

All that was checked and replaced ! Got to be something else .

i thought you said on youtube you already got a midpipe or supercat or something

Trim might be off. Might want to try resetting your ECU. How's your gas mileage? Same/better/worse? If there's spent fuel you'll know it there.

Yeah i got one to replace it but its not going to do anygood if its still going to be heating up like that

I did both resets and as soon as i try to crank it up the light is on again - gas mileage cant even be determinded right now as soon as the engine gets warm its hesistating and i cant go over 40mph

one rotor is not firing perhaps ?

I doubt that would make the exhaust over heat that much though

i have an idea,... part it out... and sell me you clear corners :]....

worth a try.

yeah cat is gone for sure....

if one rotor was not firing you will get a whole lot of unburnt fuel in your exhaust so yes it would explain it .

Uncivilized :
This all started to happen after the car wash right ?
It has to be related to water in the electrics - perhaps one of the plugs going to a coil .

Make sure that the wires are fully on the spark plugs. It has happened to others.

And if the cat is plugged you won't be able to get revs. I have had 4 replaced on my car. A miss-firing engine will cook a cat.

+1
I had 3 bad coils and i had to limp to mazda, by the time I got there my exhaust had a good bit of smoke comming from it

correct,

coil connections. not likely.

but plug wires loose or filled with water, yep.. or both..

car wash.. wow..

beers :beer:

Reason #1,376 to not go to the auto car wash

Changed out the plugs and wires and the car wont start at all shit!!

damn dude looks like youre having cat problems

Pix of the old plugs please. Can tell a lot by how they look. Will tell us how the engine is running internally.

ill take pics of them tonight , the cat is the last of my worries right now

Your cat is done, son. Looks like you had a misfire or two and the unburnt fuel lit off in the cat. The good news is, it should be covered under warranty. The better news is you could just buy a race pipe and never worry about it again.
