Rep Power: 328

Twice allready my car's engine started reving up and down out of control and it goes away after you drive for awhile?
I know of another person with the same problem.
I have intake ,headers and NOS for 6 months now, and this problem just happen a few days ago?
It sounds to me that it may be a sensor.
Any feed back will be appreciated.

This happened to my old civic, my problem was that my vaccum hose had a hole in it ( I think thats what it was called) it was connected to the throttle body to somewhere else. Also there was a screw on the throttle body that I turned to the left a little it seemed to control the RPMs of my car. Well thats all I did and it fixed the problem. I hope that helped somewhat.

I dont know if you tightened your throttle or anything, but if that cord is tightened too much it causes the RPMs to go up real high. It happened to me when I tightened mine, but I loosened it a little and it made it normal again. The nut that you probably need to loosen should have pink marker or paint dabbed on it if you want to try it. Hope it helps.
