Hello I just bought a 88 convertible Rx7. When I start it, it revs high. Almost to the three. I was wondering if that was normal? If not how could I fix it? This is my first car. I love there engines and look. Any good advice would be helpful. Thanks

 

Check for vacuum leaks?
Cold air idle screw?
Check your battery connections because the car's ecu can make it idle up fast to prevent it from dying if it isn't receiving full current.

 

Ok I thought maybe it could be a vacuum leak.
It could be the battery because its low so maybe thats it.
Thanks for the help CodyMarcus

 

RX7's have a cold start system that results in high idle for about the 1st 30 seconds. Then the idle should decrease on its own down to 700-800 RPM. If your idle remains high you might want to check the throttle cable tension.
