Why does my rx7 idle very high when I first start it?

Answer 1

Answerthe problem would probably be a leaky vacuum line to the egr-valve. AnswerYour RX7 is supposed to do this. It's the car's way of warming up the turbos quickly to get them ready for use. It should rev to about 3000rpm when started from cold if you don't touch the accelerator, and stay like that for about 15-20 seconds. If you blip the pedal, during this phase, it will stop the high revs and it will idle as normal. You'll find it doesn't do this if the engine is warm, only when it's cold.

in the late model 2nd gen cars the fast idle at start up is the choke function. esp when the motor is cold. once it starts a quick push on the gas pedal releases the automatic choke
