So far only three more reports of flooding in cars with the new PCM-update/battery/starter/plugs. That brings the total to 4.

No flooding 8/05 but I am careful.

Build date of July/05, picked up the car at the end of January. I've yet to experience hard starting or flooding, including several instances where the car was moved around the driveway. When I visited the dealer several days before delivery, it was in the service area with the hood up and the engine shield off. I assume they were flashing and doing all the stuff they should have done in 2003. It has roared to life every time (crossing fingers as I will likely pay someday for my foolish optimism).

2004 06/03 build/up-to-date flash. No problems with flooding. Recenty tested the flooding propensity. After being in a Wisconsin unheated garage - temp approx. 20 - 25F - backed it out of the garage and immediately shut off. It started right up! (of course, now that I've said this, the next time I try this and I REALLY need to get somewhere, it will be a total flood!!!)

Bump.

It has been three months now and the only incidents of flooding (in cars with all 4 starting improvements) that I have found are listed above.

It appears that the updates really do drastically reduce the chance of flooding.

Side note: MEGAREDS was told by his dealer that Mazda will do all 4 updates under warranty at customer request.

Even when the engine is warm, I rev it to 3-4 k and switch it off while the revs are coming down. Is that how its supose to be done?

In terms of flooding, the official Mazda recommendation is that the engine should never be cut off when still cold. They have documented the following procedure if you ever have to shut down an RX-8 before the engine fully warms up.

- let the car warm to normal operating temp or for 5 minutes
- rev to 3K for 10 seconds
- let go back to idle
- shut off.

There is extended debate on this forum as to whether to shut off while the engine is winding down from 3K. Do a SEARCH, if you are interested in details.

If your engine has warmed up then Mazda says that no special action is needed.

FWIW. Not everyone abides by the Mazda recommendations.

Flooding? What's flooding? 2005 GT 6sp No flooding, 20 degree weather. I've moved it a few times and turned it off too fast forgetting to rev it or not having time to let it warm up. No problems.

I haven't had any flooding issues yet, although my 05/2005 mt only has 1100 miles on it at this point. I am having a problem with a stumbling / hesitation at 6500 RPM. It'll even do it just dead revving the engine slowly.
