Took my RX7 out for a run last night.

Got home & the Idle was bouncing up & down from 1500 to 1900 rpm. It got worse when i turned the headlights off.

I noticed when i turned on the Air Conditioning on it still idled at 1600 rpm but it is a smooth idle.

I dont want to take it to Mazda because they will slug me to have a look at it. I checked for any vaccum leaks & could not here any.

Does anyone have any idea what you think the problem may be ?????

Yeah there is not much there that helps me. Thanks anyway.

I only have the problem on idle. Normal drivng it is fine.

Someone has told me the Idle Up Solinod near the firewall on the side of the throttle body.

 

The Idle Speed Soliniod? I think thats stated in the the link I gave you. Well anyway www.turborx7.com has a some manuals you can look at on how to troubleshoot the ISC.
