sup guys, I have a 91 CRX Si, and when I start stepping on it, the tach needle just jumps all over the place it's really annoying anybody had this problem before?

 

yeah it's becasue almost all stock tachs suck, even hondata's Integra does it

 

take the cap off and tighten the screws, it worked for me

 

the dizzy cap

 

Or it could be your ignitor, I would replace it and see if that fixes it.... It did for me.... That sends the signal to your tach.

Yup, most likely this. Before buying one (like $80-90) pop off your cap and check all the connections there, theres 4 wires held on by spade clips. Just make sure theyre snug.

 

I had the same problem, after replacing the ignitor and cap the tach was still bouncing. So i finally got around to changing the rotor and it solved the problem.

I would suggest changing the cap and rotor first, it's only like 20 bucks for both. If that doesn't work try a new ignitor.

 

Ignitor without a doubt, its going out/getting false signals.

 

thanks guys, I got a new cap and rotor on it already, so I'll check the connections on the igniter. Thanks!
