Well, I have an 88 TII, actually it's a 10th Anniversary, but I don't think that matters.

I'm having electrical issues, all the parts are stock short of the stereo and the sunroof (tempered glass put in place of the white metal).

Cut to the chase. THe car idles at around 700 rpms, and when I do anything electrical (step on the brakes, turn the wheel) at idle the headlights will dim, all the dash lights dim, and the RPMs drop by about 200. I don't know what it could be, I checked the battery because I recently had to replace my starter. It also has a tendency to die soon after being started when it's warm, on a cold start it starts up and idles at about 3000 until I tap the gas and it goes back down, also shows lots of hesitation off the line.

Any help you guys could offer would be GREATLY appreciated

 

U could have a gas leak. Try getting the idle at 900 so it wont die off. And ALL RX-7's rev up to 3000 RPM for about 25 seconds when they're cold. It's the AWS (accelerated warm-up system) If u wanna bypass the AWS start it in gear an jus leave ur clutch on the floor for about 30 seconds. Or jus get the haynes an take all that **** out

 

U could have a vacuum leak. Also could be the injectors if u got weak power. Try getting the idle at 900 so it wont die off. And ALL RX-7's rev up to 3000 RPM for about 25 seconds when they're cold.

Check alternator ouput. it should be around 13.5-14 V at the battery posts. When you put elec stuff on, it should drop but not too much.

Your hesitation could be a misadjusted TPS.
