I did all the basic maint. stuff to the car when I got it. New oil, filter, radiator flush. I also put on new battery terminals since the old ones were pretty rough.
The previous owner had put in new plugs and plug wires.
The car is hard to start, and I usually have to run through the deflood steps to get it to crank up.
Once it is started, it idles just fine and I can drive it around w/o incident.
On occasion when driving if I let the RPM get up to high, it will put the check engine light on and then limit me the RPM's down to around 3k or so. Turning it off and starting it back up clears the engine light and enables regular driving again.

It could be clogged fuel injectors.

If they are dirty and sticking open, when you turn the engine off, they will dump fuel into the engine...

Too much fuel will not burn because there's no oxygen. Hence you have to deflood.

It is interesting that you mention that the check engine light comes on and your RPMs are limited. I am curious what code the ECU is throwing when the check engine light comes on. You have an S5, so it could very well be entering limp mode for some reason. Does the car buck if you try to give it too much throttle when the check engine light is on? Check the codes stored in the ECU next time it does this. How to do this is below or can be found searching the 2nd generation technical sub-forum.

i had an 07 gti that was flood damaged all that was done was make sure there was no power to anything until it was stripped and dried completly,alot of electronics in a gti never had a problem,although a wierd moldy smell when ac was used,antibacterial spray solved that thats on top of what you have already done of course

Just so you know, deflooding is a procedure that removes the excess gasoline from the combustion chambers. That is what the original poster is referring to specific to the RX7.

Sorry but it sounds like you need to get the injectors cleaned or replaced. Not the cheapest of ways to go but really about all you can do if you want it fixed and do not want to have to deal with a bunch of kill switches like my last 2nd Gen. It seems to be a pretty common issue on these second gen cars.

Just finish up with your 'tune up'. you got most of the items on the list, just finish the list. your car should be running fine then.
