Why does my RPM jump up and down?
Hi. So I recently got my first car and noticed as I'm in neutral going down hill the RPM would jump up and down and seems to stop as I'm braking and stop. What should I do? Oh I forgot to mention I have a 93 Civic HB VX D15Z1.
Thanks.
Thanks.

No engine check light.
I'm very new to this so will this be an easy quick fix? What do I need to do to fix my IACV?
Thanks for the quick response.

If it is the IACV, you can try cleaning it before replacing. Just follow this guide: https://honda-tech.com/forums/showth...+control+valve

Yea. My wording was a little off to make it sound like the light wasn't working, but would the CEL turn on with my RPM problem?
How'd you know it was your speed sensor?
