1991 Mazda rx7 the 12 motor-after choke is off it will not idle and spraying ether does not raise idle so do not think it is intake leak but rather an adjustment have no manual HELP?

It sounds like your 1991 Mazda RX-7 may have a problem with the idle air control or fuel delivery system, especially if it won't idle after the choke is off. Check the idle adjustment screw and ensure it's set correctly, as well as inspecting the throttle position sensor for proper operation. Since spraying ether doesn't raise the idle, it indicates that the engine isn't getting the necessary fuel, so also check the fuel pump, fuel filter, and injectors for any blockages or issues. If you can access a repair manual online, it may provide you with specific adjustment procedures and troubleshooting steps.
