Recently joined the RX-7 Club....I'm having idle problems. It keeps reving up from 2,000 to 3,000 rpms
all erratically. Checked the TPS sensor and it all checks well. Just hoping on an insight on similar issues anyone is having. I recently swap out the engine if anyone can maybe show me pics or vids of important vacuum line hoses.Trying to get this girl on the road any help will do thanks. She's a 86 Non-Turbo.

 

Man I was hoping to receive a reply by now over 200 views no reply....

 

How did you check the TPS. Have you tested for vacuum leaks? Is the throttle cable adjusted properly? When was the last time the car idled properly?

 

Stock ECU? Sound like it's hunting?

 

2 days ago started her up with no problems. Now she starts up and idle goes up 2500 to 3000rpm just bouncing. New radiator and she's heating up. I did exactly what the manual said with the tps got her at 1000 ohms. I want to take her out for a spin but don't want to do major damages. She's my first crush ( Rotary )...As soon as I can I'll post a vid and paste so u can get a better idea of what's going on...I myself am more of a visual person... I figured someone has had a similar issue and maybe let me in on a little insight. Knowledge is what I crave to get this started..Thanks to all

 

So I figured what happened....the headers weren't bolted on tight enough an was the cause of it sputtering up and down from 2 to 3,000rpm.
