I drive away as soon as it starts, and never rev on shut down.
Idid flood once, got latest flash and a addin for the owners manual, which say rev to 4000 rpm before shutting down, but this only apply to a cold engine.
been getting just over 22 mpg since flashed about 1 mpg up.

 

I had my hardest start today. Seriously thought that it might not go. I had my car on the driveway and wanted to move it into the garage cause the weather was supposed to get bad. So I figured I'd go fill up the gas tank, and then put her back in the garage. But because I was in a rush to get to work, I went to the closest Shell station, which was less than 2 miles away.

I REVVED to 3,000 rpm on everyone's recommendation, turned the car off and filled the tank. When I went to start the car, it took a while to start, but managed to get it going. I wonder what would have happened if I didn't rev? It would have sucked to be stranded at the gas station...

 

Yep Idid try it once after it was flashed had same problem won't be doing that agian.
2 miles should have warmed the engine up enough.

 

im so use to of reving my car .. that when i drove my mums truck the other day (auto)

i reved that too... :o

 

I never wait for the car to warm up before driving. Once the idle stabilizes I am off.

I have never rev-ed a car at shutdown in the past. In most cases I don't rev the RX-8 at shutdown either. However, based on Mazda's recommendation, if it was a "short trip" I do follow the procedure they gave on the DVD:

1. Let the car reach normal operating temperature or idle for 5 minutes.
2. Rev to 3000 RPM and hold it there for 10 seconds
3. Let the engine return to idle
4. Shut off the car

 

yeah i just wait about 2 mins on a cold start then drive off slowly not pushing the car. and no i dont rev it before i shut it off and its fine.

 

I used to warm up my car before I start going, but now I start then go. I always rev my engine before shut down I only have done it maybe 5 times and once it flooded and when I dont rev it the next start it starts choking.

 

I've just had my car for 1200 miles and today I drove it about 30 straight miles home. Upon
turning the car off I heard a "thump, thump" noise coming from the back. I turned the car
back on and stepped on the accelerator and it would thump a couple of times pretty
loud. It never did this before! Is this "flooding"?

Also, my oil light kept coming on and off every minute or so. I'm sure I just need to add
oil. (HOW MUCH?)

Thanks guys.

 

Flooding is when the car won't start because of excess fuel trapped in the engine causing problems with the spark plugs igniting the mixture or causing problems with the apex seals sealing so compression can't be achieved.

What you describe sounds more like a backfire (fuel detonating in the exhaust system). You should have your dealer check it out.


Add oil until the dip stick shows the oil-level at the top of the range. I think it is 1.25 to 1.5 quarts if you are at the low mark (someone who knows correct me on this). Avoid over filling.

 

I can pretty much say the same thing. As a rule, I wait until the RPM's are holding steady at 1100 or so. Regardless of the weather, it takes about five minutes.
