Welcome to the rotary world. Enjoy! The only way to fix it is put a nice rice b16 in it. Other than that its the nature of the beast, so drive it loud and proud.

 

First, full tuneup. Plugs, wires, filters, TPS adjustment, etc. etc.

Injector cleaning if it has never been done before (almost always the case). Ultrasonic is best, done by a professional shop.

While I rarely recommend aftermarket parts to "band aid" problems, an S-AFC is a great investment as it will allow you to lean the car out (all NA RX-7s run very rich stock), save fuel and pick up some power as well.
