I have an 89 RX-7 non turbo and my Idle hangs out around 1500-1000 and when I turn my A/C on and off really fast my Idle will return to normal again. How do I fix this???

Check charging system, grounds, bac, vac leaks, etc

Set TPS and Adjust the idle according to fsm

see my web page (in sig) under 'my own faq' and 'idle' for ideas (it's for NA s4 but should apply to s5 somewhat)
