Surging W/ a low idle?
I am quite new to 1st gen rx-7’s and i’ve been having issues with my idle and just fuel/air mixture in general. The car is running very rich and the idle is sitting extremely low. I engage the choke and make sure the car warms up before attempting to to tune and I’ve been trying my best to use videos and such as reference to how i should tune it and i’ve had some decent success with bringing the idle up at least, but i can’t seem to stop the car from dropping in rpm’s and surging whenever i give it a little gas.

welcome to the board. 
1. follow the FSM procedure to set idle via the idle speed and idle mixture screws
2. check the accelerator cable and throttle shaft - make sure they are not binding before returning their respective resting positions
3. check for vacuum leaks
4. check the timing with a light
