Idling at 2grand!!!!!!!!
Hey, I have tried and tried to change my idle because I just bought an 87 rx7 and the car was idling at 3grand at first. However, after I changed the radiator and alternator and belt and crap it dropped to only 2grand. To be honest I'm not sure how they are related to each other because I am new to working on cars and I am doing everything from an rx7 rebuild manual. I tried turning the idle screw all the way down, but it only went to 1.75rpm.... so if anyone can help me I would greatly appreciate it because I dont want my engine to blow because it is pretty good condition and only has 50K on it... which is like new to me.

From the FAQ at the top of this page.
My RX-7 rev's up to 3000 RPM everytime I start it when cold
Yep, part of the accellerated warm up process. Start the car with the clutch pressed in, and the car in gear if you don't want it to do that.

Check for a vacuum leak. All the lkittle black hoses that go aroudn the engine, make sure they all are connected and not leaking. Also, make sure you have the OEM mazda Thermostat.

Wouldn't a vac leak cause fluctuations more than just a mere high idle? On top of the TB/dynamic champer, there is a black cap, take that off. Under that will be a screw, this is your idle speed screw. Tighten it to make your idle go down, loosen it to make your idle go up. Of course you can only tighten and loosen to a certain point, when it gets hard don't force it, just stop. If that doesn't fix it there's more things to try, but give that a shot for now.

According to his profile he has an SE, so it's non-turbo. N/A's dont have the BAC idle screw, we have one that is on top of the tb/dynamic chamber.
