What do you guys think about this revving to 3k before turning the car off thing? I've been doing it for so long and it's gotten to be such a habbit that I do it to my gf's car when I drive it, and she always gets mad at me for doing it for some reason. Everytime I do it in the parking lot in the morning and someone's near me they look at me, makes me feel like they think I'm showing off or something.

Anyway is it really something I should still be doing? Am I asking for a flood if I stop doing it? It's not that it's driving me crazy or anything, I'm just curious.

I do it whenever I can, but I've turned it off when it was warm w/o revving and it started up fine. I'm probably just being overly cautious.

I'd only worry if the car was cold as long as you have the new battery and starter.

Despite knowing about this procedure, I've never performed it, and have not flooded either. Its not too difficult to allow the vehicle to warm up before shutting down for me I suppose

It's become a habit for me. I never flooded before I did it though either. I do feel I get smoother starts when I do it.

I will confirm this when I get my car back (manual is in glovebox, car at bodyshop), but I am fairly sure that this "procedure" is only meant to be done when you just intend to leave the car idling to warm it up before shutting it off to avoid possible flooding.

CarAndDriver

Yes, it was largely introduced to prevent flooding when the 8 is going to be shut off before getting to op temps.

However, it was intended to flush excess gas out of the chambers when turning off the car and the 8 seems to be prone to having some problems if too much is left in there. Just doing it on a regular basis would seem to be a smart thing to do. Its not going to hurt the car as far as I know.

they even say that the only reason you should need to do this would be when you don't have enough time to warm the engine up. I've never once did this after the engines been warmed up, and after 11K miles, not a single problem.

There's even been a few times i've turn it off when it wasn't completely warm without doing this, and it started up just fine.

CarAndDriver

So anyone come up with a reason against doing this after the car is warmed up? Other than wasting a little bit of gas or making people next perhaps look at you?

never done it - never will . Have shut engine down cold (moving it out to wash etc) lots of times & never had a problem . If I ever do have a problem I know what the deflood proceedure is & will deal with it .

BTW mine is a 2003 model with none of the anti flooding updates until I recently did the spark plugs (due for replacement anyway)

I never do it.

I do it, but I flooded once even with this procedure (Had to move the car so a guy could get in the garage to install FIOS). Car refused to start once the FIOS guy left... didn't start the next day, had to call for a tow truck.

I have no faith that this procedure will save you from flooding. Doing it for years and not flooding does not mean it works. That logic would mean smoking doesn't kill, if you're a smoker and haven't died yet


Best way to prevent flooding is to make sure you don't start up the car, move it 10 feet then shut it off.

i never flooded until i installed the basemap int-x and moved it without warming up. and it flooded. but thats the only time i have ever flooded mine

CarAndDriver

Agreed--drive it around the block or let it idle for a few minutes to let it warm up.

I did it a few times on a warm engine and actually it had rough starts afterwards. Once I was almost sure it flooded before it finally caught up. Now I never rev it up before shutdown and it starts easy. I always make sure the engine is warm, though.

SmokeyTheBalrog

Here is a question, do you turn off the engine while your revs are climbing or after you release the gas and revs are dropping?

I always do it while revs are dropping.

I don't think it does anything major besides hopefully keeping the apex seals from sitting in gasoline.

CarAndDriver

Dropping.

mysql101

once you shut off the engine with the key, depress the throttle all the way down.

CarAndDriver

Why??

mysql101

why are you reving it?

CarAndDriver

Huh?

The whole thread is on the potential flooding protection on revving the car to about 3-4K and then shutting it off so it flushes any gas out of the chambers and making the car easier to start the next time.

Now WHY would you push the throttle down all the way after you turn it off?

mysql101

Exactly. Now what happens when you give the car full throttle?

CarAndDriver

More gas goes in.

mysql101

Fuel pump isn't operating when the car is off.

CarAndDriver

Well you didn't specify on or off.

So you going to explain your logic? The 8's throttle is electronic so it shouldn't do anything when the car is off.

I have never flooded mine either Brettus and i have shut of cold quite a few times, i even stalled it cold after i just turned on and it didn't flood. Seems the U.S cars are more prone to flooding perhaps?
