Yes, Yes, Yes...I do have the latest M flash, had it for a while...when I took it to McCurly mazda, they said that they fixed the flooding and reflashed it again... with the latest m flash type upgrade...I guess its what all the recent talk is about on this board. Oh well.
I did start it, pull out then went back in, idled, then turned it off (2 min).. Keep in mind, this is my first flooding after owning this car, and have been careful in the past.
I will have to be more careful I guess. I hope (wont hold my breath) that this latest reflashed, M flash, flash updated flash flash, will do the job.

Two weeks ago my car was flooded. I only moved it 1 minute two nights prior and when I came out that Thursday - nada - what a pain.

I shut my 8 down cold when I wash it and shut it down cold again after I park it back in the garage. I've been shutting it down cold this way for over a year now and have never flooded it. However, I rev it to 3K RPM before shutting it down. Also, I've been using the same cold shut down procedure on my FD for years and have not flooded it either. The closest i've come to a flooded engine is a strong gas smell from the exaust after the third start up. I know that I am pushing my luck but then again I am also prepared to unflood the engine myself if I ever have to.

I don't see it listed on Tommys site but there is a bulletin (just released) to upgrade the battery to 640 cca..

Hopefully this will prevent some of the flood issues by keeping the cranking RPM high on cold starts.

P.S. Sorry for your bad day cebat.

Hey rick, better go find some wood and start knocking. That is the same exact thing I would have said before a few days ago before I joined this club and became president.

Rick

I already did that Besides, we live in the same city and are members of the same forum so the odds of my 8 flooding too must be near impossible

I've not had a flood problem but thanks to this forum, I am very aware of getting the car warmed up if I start it up. So, when I pull it out of the garage to wash it, I roll it out without cranking. Then, I'll leave it out untill I have to go somewhere or take it for a short ride before pulling it back in. My car came with the M flash.
This forum has been invaluable to me and I am sure to many other RX8 owners.

My gauge seems to read three positions:

1. completely cold
2. approx 1/4 from cold to warm (partly warmed up, I guess)
3. approx 1/2 between cold and warm (normal position when operating)

The time it takes to reach #2 and #3 varies with ambient temp and how long car had been off. cebat, had your engine temp gauge moved at all when you shut down before it flooded?

Dark8

I can't be the only person that lets the car idle and warm up as I wash it? :p

As usual snap-on's point is dead on. The battery is a key part of this equation. If you don't want to flood, make sure you have the latest flash, that you have sufficient battery power and that you don't have fouled plugs from excessive slow driving and short trips. The battery is very important. I think they all come with the 640 now. You don't want to know what the old one was rated at.

well, uhhhh, no my temp gauge didn't move Deslock...my car is flood proof remember? Yea, I know I am an idiot for not allowing it to warm up. Now I know. Kudos to everyone who is more deligent about this than I.. You are saving yourself a lot of hardship and embarrasemant. Mazmart, very good point about the battery, I never looked at it that way before.. My hope as others read this thread, who are becoming lazy about warm up procedures, is that you will stop and think...and say to yourself, "Do I really want to join Cebat in his stupid club?"

SoundzPlusInc

Sad to say ... I am a member of this Club ..

Had to have it towed in - All new plugs ..

Major Pain in the Azz .......


Made the mistake - short move - Short warm up -- NEXT day - Wouldnt start PERIOD/

I just got back from a 6 day vacation tonight and went to drive my 8 and it flooded. I live in Indiana and it has been relatively cold here and my 8 was sitting outside while I was gone. Before I left for vacation, I had driven it home from work, about 15 miles, so I don't think it was that the engine wasn't warmed up. I believe that it was the battery issue. It cranked very very slowly and would not start. I had to get my wife's car and jump it, it took me about 10 minutes using the dechoke procedure to finally get it started. I have had my car since Feb and never had a problem with flooding. Well I take that back, the dealer flooded the car when it was on the lot. It starts fine now, do you guys think I should take it to mazda and have them check the battery and/or the plugs? I have the M flash.

Thanks,

Boilermaker

Deslock

LOL. Well, I wasn't saying that with my post... I've been in the situation where I wanted to shutdown, but my temp gauge had only moved part way and I didn't know if I still needed to rev it at 3k RPM for 10 sec or not.

Has anyone flooded with M flash when the temp gauge had moved? (not counting instances of a dead battery)

6speed8

I have never had mine flood and most probably never will because I have never (even with my piston engined cars) started my car moved it a few feet then shut it down. I have always let all my cars warm up before shutting down, this prevents condensation buildup in the oil on ALL engines. I might spend a few more minutes with my cars running a burn a bit more fuel, but I have never had an engine failure in 30 years of car ownership. In light of the rotary's ease of flooding, I would say my habit will most likely be a true benefit (after 30 years - lol)

Last summer, I thought it would be fun to drive my 8 through Rocky Mountain National Park. The idea of "snarling" over those mountain roads really appealed to me. I was driving in 3rd gear at 4000 RPM and the engine quit. According to my GPS, I was at 11,400 feet. There was a strong smell of gasoline. I managed to get it started in about 10 minutes. This time I ran at 6000 RPM in second gear. I had to slow down to 4000 RPM for traffic and it quit again even in second gear. Again after about 10 minutes, the engine started and I ran in first gear at 7500 RPM until I got to the top at 12, 400 ft. Obviously, at that altitude the"snarl" became a whimper. The engine flooded because it was set too rich. I took it to the dealer and they did an M flash. I have had it at 10,500 ft since and it ran well. It had good throttle response which it didn't have just prior to quitting the first time. Has anyone had a similar experience?

My gas mileage increased from 23 to about 24 on the highway after the M flash.

RX Renesis

they shouldn't give u the M flash... isn't that flash suppose to be on hold cause it causes other problems?

New member here! I've had my 8 for a year, never flooded, but today was the day! Did the following as recommended: foot on the floor, crank for 10 sec. wait for 15 then repeat for a total of 4 times, then foot off gas, crank... started right up. An awful stink of gas out the exhaust, but otherwise no lasting problem. The car has M flash, but that doesn't make you immune. It is important to repeat the de-flood foot on the floor procedure 4 times, less did not work!

Happy holidays!

rx8cited

Mine's never flooded in over a year ...... I hope my day never comes :D. Any idea why it flooded (short trip)? Glad to hear you were able to start it yourself. Happy Holidays to you too!

My car was flooded last night. I am aware of making sure it is properly warmed up before shutting off, as well as no very short "move the car from the driveway to the street" trips. I also know about the rev it at 3500 for 10 seconds.
My question is: Can flooding ONLY be caused by the turn it on and shut it off quickly deal?
Last Saturday the car was out for a few hours, washed, and parked. The next day I drove my wife to work (5 minute drive), followed by a 15 minute drive before parking.
The car was then parked and not driven until my wife tried to start the car yesterday. It has been cold (-30ish) but the car is parked in an attached garage with a temp of about -9.
I was at work and did not witness the starting proceedure.
She claims that the car "made the starting noise but wouldn't start....it sounded funny".
Now I know sometimes it takes longer to crank than a regular car, and she may have let go of the ignition before it fired up, or perhaps she even pushed the pedal down a bit when cranking.
Is there anyway she could have flooded it? I thought it had to be running and shut off too soon for that?
Anyway I got home in the morning, and sure enough after about 10 seconds of cranking no go. It really did sound funny. Turning ober and not catching.
3 rounds of 10 second cranking with a floored pedal, and a few normal 10 second cranks (needed to boost while doing this) she finally started.
The check engine light was on until the smoke cleared.
A nice 45 minute drive on our perimeter highway (100-150 km_and all seemed good. I stopped for fuel, and drove another 10 minutes and the light came on again. I will recheck the fuel door. Usually a fuel door will give the engine light up right away.
So, basically did she flood it while starting, and what about the engine light?
Due to the flooding?
It boggles my mind. I knew about the flooding problem, and feel that everything was done right on my part.
I love the car. I can deal with bad gas mileage, and needing winter tires.
Having to deal with the flooding deal really is enough for me to sell the car.
We can put men on the moon, baboon hearts in humans, but my car cant be started by a "soccer mom".
Who knows, maybe there is a problem with a sensor or something.
I dont want to come across as sexist, but most of my car problems that involved a female, were usually a result of the female. (an old girlfriend drove my car and put a litre of oil in it simply because she thought you had to add oil after you drove a car for a bit!)
Of course it had to happen while I was at work.

Any thoughts?

Merry Christmas/Festivus!

After several attempts to find a flood thread...behold

Lets discuss it there.

Please?

I edited your response to correct a typo!

Thanks for the link to one of the many useless threads I have already read.
As stated above, my car was not in a situation that typically causes flooding.
Is it possible to flood the car by doing something different than shutting it off too quick?
None of the flood threads cover my situation.

bean438

Several seconds eh? As I said, I searched. My situation was not covered in the many threads about flooding.
The flood threads cover "I heard the car floods, is it true? I was gonna buy one but the flooding.... how long should you warm the car up?.....m flash, ya got the m flash?....will the m flash stop flooding?.......
Your 2 posts suggest how easy it is to search, and the implication that I did not do that.
I am very dissapointed by that.
Why respond at all if you really cant contribute anything usefull?
Combined posts of around 1600 and thats the best you can come up with?
