Check the Idle and the timing. My timing was dead on after I set the idle, but that idle was way off. That made it run like crap. After adjusting that, mine runs like a scalded Ape on Acid.

Well the power sounds like the pri, injectors are clogged or something. They don't seem to be working right, 3800rpm is where the sec injectors come on line.
As for the whining, it sounds like the tranny. Mine has a little whine as well, but i would change the tranny fluid in yours for sure.

first thing you need to do is set the idle. You will need a Tach to do this (not the one in the car). there's a set screw on the top of the intake covered by a rubber stopper. set the idle to 750RPM. then set the timing. check the Haynes manual for how to do that. once it's all setup it should run a lot better. At least it did for me.

Sounds like your flooding it. before you shut it off, push the throttle to 3000 RPM and then turn off the ignition. hold the pedal there until it stops. you should be fine then.

That whinning noise is probably the bearings inside the transmission. You should take a look at the fluid in the trans and make sure it is in good shape and it is full. If you want you can try and replace the fluid with some Lucas transmission fix and automatic transmission fluid. I did that with mine and it helped shifting alot. I don't know if that will fix your problem but its worth a shot and may save you from replacing the transmission. As for the no power untill 4 grand check the 6 port induction actuators on the passenger side of the engine. Mine siezed up so we removed them and my car does that exact same thing. Just a trait of the rotary engine. They hate low RPM.

I would just use lucus if i was you and some good synthetic fluid. (amsoil is what i use).
To me it sounds like an ECU problem that is causing it to advance the timing when it should not.
Have you checked the TPS?

Automatic transmission fluid is fine to use in a manual transmission, in fact that's what alot of vehicles now come with from the factory. If you read either on the back of the bottle of lucas or on thier website that's what they recommend to use on a manual transmission. Put a whole bottle of lucas in and top it up with ATF. The only problem I ran into was trying to get the lucas into the transmission because that stuff is like corn syrup. It's REALLY thick.

Wow that is terrible mileage. There is definitally something going on with the fuel control on your car. RX7's don't get the best mileage but I can pull off like 30mpg if I cruise around 60mph on a trip. Even when I'm hard on it it gets like 25mpg and its the same car, 1988 NA GXL. I'd be getting your injectors checked, you may have one thats stuck open and it's just dumping fuel into the engine. If that isn't it you're gonna be into looking at sensors.

What you can do is try and hook up a fuel pressure gage on the fuel system. I'm not sure if there is a test port or not. Turn the key on so the system has pressure in it and then turn the key off. The fuel pressure should drop a little bit but not a whole lot. If it drops fairly quickly and/or goes right down to zero, chances are you have a leaking injector. As for adjusting the fuel that's all controlled by the computer so there's not a whole lot of adjustment that you can do.

Try this site for some good information on how these motors work and how to set them up. Look in the FAQ for the procedures on how to take care of the flooding problem. I do also suggest that you get a book on the car. even a haynes manual will guide you through the steps to setup the car. These are nothingf like most of the cars you will find and I have found that there is a lerning curve to understanding how they work and how they tune.

i dont think my primarys are working right cuz it said the 2nd daries dont kick on till 3500 rpm and thats about when i get my power....it could be they are clogged from the old gas the guy had left in there...so know they are stuck open or clogged...imo....but then again it also said it was all electrical with the injectors...can they still be clogged and letting fuel drip into the motor when its off...
