Shutting your car off.
Hello everyone just curious if it's ok to shut your Rx8 off normally after it's warm of do you still have to rev the engine at 3000 rpm for 10 sec to keep it from flooding . My car seams to start fine if I shut it off normally as long as it's warm or after a long trip.

How do I shut off an RX-8?
This somewhat ridiculous question keeps popping up recently. Other than the obvious "turn the key counter clockwise and remove", there is literally nothing special that you have to do. You will find people that insist that I am wrong in making this statement, but no, it is just that they are taking one symptom and extrapolating preventative measures even further off base than they already were. For example, you will find people that swear by reving the engine to 4,000rpm in neutral and cutting the key out there, with the revs up. They are doing this under the assumption that the faster spinning rotors will help sweep excess fuel out of the rotor housing, to prevent a flood. The problem with this idea is already explained in the Flooding section above. If your engine is already warm, there is no excess fuel being dumped in! (Except perhaps the fuel needed to rev to 4,000rpm). Shutting it off at 4,000rpm is no different in terms of fuel than shutting it off at 750rpm. If your engine is currently cold, then this could only POSSIBLY have an impact if your ignition or starter or battery is failing, in which case 'yes', it might help prevent a flood. But a flood is a symptom of another issue anyway, and only happens on START, not on SHUTDOWN. |
Thanks didn't get a chance to read that but I figured the most just wanted to check with a few of you guys .
|
I turn the key from "On" to "Off."
|
I close my eyes and pray... :suspect:
|
Drive it just like any other car purchased in that year. If it gives you trouble then get the maintenance done to fix it.
|
I keep seeing that you should be able to kill it even when cold unless you have an ignition failure, and yet is that really how you want to find out that you do have one? Even a brand new coil could possibly have a manufacturing defect. I think I'd rather see the CEL flash for misfire than get stranded at the grocery store at midnight hoping like hell I can get someone to jump me off, so I do as Mazda says and only kill it when warm.
|
Id rather find out while stranded at the store.
Otherwise youll find out when your cat is clogged and your engine fails. Which is worse 40 dollars for a jump start maybe 150 for a tow or 5k for a engine and cat? |
I have no cat so I'm not worried about that.
If you do, flooding it would kill the cat faster than anything else, but I guess at least you'd know to quit driving it before destroying the engine too. I guess the question is how long does it take for the ECU to indicate a misfire, and is the damage up to that time worse than the damage done by driving it home once after flooding it? ETA: I didn't read your last line. I must have thought it was a signature. Who can you pay to jump off the car? |
Is it possible to pass an emission test with no cat ? I live in Washington state and they make you pass one every other year. I read a lot of you have no cat.
|
It depends on your emissions regulations for your jurisdiction.
Where I live in PA there is no emissions checked, so passing it is easy. The last place i lived had OBD2, and passing that is easy with a reflashing tool that blocks the right CELs from ever appearing. If you live in California, you can't pass without a cat. Other states, you may or may not be able to, depending on the exact wording of the regulation. |

If the first sign of ignition failure you have is not being able to start the car after a cold shut down, or your cat clogging...
You aren't paying attention. The signs will exist WELL before that. Most of us have been guilty of ignoring or not seeing the signs ahead of time at least once. For my part, it cost me my cat, and my engine. |

Most tow trucks offer roadside assistance. Jump starts, 5 gallons gas, changing tires. Texas even has a number on the back of your license for it free. They'll give you a 20 mile tow for free.
That's only if you're on a public road though. If you're in a parking lot, I guess you better push it out to the street. |
