Check that on your carburetor, when you press on the throttle, it still shoots a little bit of gas out into the barrel. If it does not, you may need to replace the throttle pump. what is happening is this: As the throttle is opened higher, the vacuum drops severely, and the fuel doesn't get put in. The throttle pump pushes a little squirt to retain the vacuum. If it is an EFI unit, you have other issues, that I would recommend a mechanic for.

83 Rx7 stalls when cold unless I keep applying pedal pressure


these cars are carburated motors and need around 10 minutes to warm up because they operate at higher temperatures.

Have a 1985 mazda rx7 will not idle .. cold start ok when choke is on once warm stalls and will not idle


There is a throtle adjuster right behind the carb. You can adjust it with a screw driver. If you are not sure where it is, just have someone press to gas pedal and you will see it move. RPM's at idle should be around 1,000 when it is idle once it has warmed up. Once that car warms up the choke moves back in and the car is probably stalling because it is not running enough RPM's.
