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.

What year is the car and if it's an 84 or 85, is it a GSL-SE? This will help us get you going in the right direction.

The car is a 1985 mazda rx7 S. Srry for not including it in the post

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
