Engine Flooded? Car starts but idles wildly and acceleration pedal doesn't work!
Hello all, I have had my RX8 for 5 years.
Today I started the car, didn't really let it warm up. Drove on to the highway and hit it in third gear and all the sudden the car started to idle wildly and the acceleration pedal does nothing. Very strange. Was able to get off of the highway and the car wouldn't start.
I thought maybe it was flooded and tried the procedures but nothing. Waited about a half hour and the car started but idled wildly again.
It idles like a heart beat. Very strange. Had it towed home now and wrting this.
Searched on the forum but nothing on the acceleration. Only loss of power issues which would still leave the car being able to accellerate. When I press that pedal nothing happens. Just the idle is crazy.
Has anyone had this type of situation? I am going to call Mazda but they are not open until Tuesday I believe.
Thanks for reading and my appreciation in advance for any help.

I am in New YOrk. Problem is I got it started again later on after it was home but it just idles the same way and no acceleration. When I hit the gas in neutral or in gear no revs.

Battery was replaced as Mazda replaced it twice but still was a piece of crap. Bought a cold cranking one at autozone last year and works really well.
Thanks again, really appreciate the tips. I will try it out in the morning and report back!

I had a similar Problem, do you have a CEL? For me the problem was my pedal position sensor, i ended up having to get a new pedal from Mazda. FYI if this is that case, there are 2 pedals one with the aluminum pedal and the other with a rubber pedal (GT vs. GS Models) I would imagine that all internals are the same although mazda originally quoted me for the rubber pedal and then ordered me the aluminum pedal, after a big ordeal with them they credited me the difference. And the difference in price is rediculous.
Rubber pedal = $144 Canadian
Aluminum Pedal = $378 Canadian
I couldnt believe it, the only difference is the little screw on aluminum piece in the pedal which you could just transfer over from your old one anyway..... Hope this helps

Yes CEL is on when the car is started and idles like crazy. I can't believe it would be a foot pedal sensor. That is crazy.
Thank you for pointing this out and once I try Swoopes method I will post back. Hopefully in the end this will also help another RX8 owner from what I find.

Just Got back...
I haven't pulled any electrical connections recently.
This all just happened.
So I went to the car. Charged it up. Disconnected the battery and did the brake thing.
Started it up and still the same. No acceleration and still the crazy idle. From 2500-3500 RPM and just keeps going every second like a heartbeat. Lots of nasty smoke but nothing like a decarbed or flooded engine.
Lots of popping.
So I don't know what else to do and probably have to get it towed to Mazda. I use my dealer in CT which is an hour away and the tow is $300.00.
I had a bad experience with Great Neck Mazda so I don't know of any Mazda dealer in NY that I can trust. Car is low with the full MS kit so I am paranoid.
If anyone can help please let me know. Once again, thank you for all those who responded.

I once accidentally started mine with the mass airflow sensor unplugged, and it idled rather erratically.... I think others here probably have some more solid advice here, but if you haven't checked that, maybe take a look there. I never tried driving it with the sensor unplugged, so no idea what it would do when driving....
