1990 Mazda RX-7 - Engine shuts down

when the weather is hot after 10-20miles the motor shuts down and will only at rev at 2000 to 2500 rpms the motor but can’t be driven

So it’s going to Limp Mode. You’ll need to figure out why (overheating, CEL on/flashing, Transmission issues, etc given the lack of information about your car such as mileage, have you tried anything, etc we really can’t give you anymore advice).


Few people have any experience with a rotary engine and you will probably have a hard time finding anyone with that experience as they have been out of circulation for many years now .
