I have a 1985 13b rx7. The servos or whatever that are ran by vacuum lines on my lower intake manifold were gone when I bought the car. So being the smart person I am I went in and took out the cylinders that they turn inside the two intake ports that control how much air goes through the port. The more air the better right? WRONG. Its STILL running horribly. Will someone PLEASE help me figure this out. New to rotary engines so its very frustrating.

the missing parts are the actuators for the 5th and 6th ports. they run off of back pressure from the exhaust. they require a tube similar to the split air pipe, running from the lower intake manifold to the main converter. you need to reinstall the 5th and 6th port sleeves which you removed and get a working set of actuators.

Now I'm not a GSL-SE expert but from my reading I'm gunna agree with mazdaverx713b on this and say definitely sounds like the aux port equipment is not working and even just plain not there, it also sounds like you pulled the actuator sleeves out which I'm told leaves alot to be desired down low. Get the aux ports functioning and it should sole the problems.

4 on a turbo, 6 on an N.A. You can most likely find your parts here, in the FS section.
