Hey, I have a 95 cx hatch, and recently i swapped the cluster from an ex/si in order to get a tach. it treated me well all summer but now as its getting cold (no idea if that does anything), the tach is having issues. I have read about the dancing and bouncing tachs but nothing like mine. Sometimes it will work fine and other times it is super inaccurate. Like ridiculously bad. when the tach is having issues, the tach stays at 0 rpm untill the car is at about 3k rpm (a guess by sound) the tach starts to move and very very quickly will go to 6k rpm. its like the "range" of the tach is limited to 3-4k rpm but shows values from 0-6k rpm and i have not idea what it might be... thank you for all the help in advance!

 

Any CEL codes?

Could be a bad igniter unit or poor contact of the blue rpm wire with the prong of igniter unit inside the distributor.

 

No check engine light codes. Okay, where would I find the igniter unit to check? I assume the unit is inside of my distributor, but i am not sure what it might looks like. I replaced my distributor this summer because my car was running rough, and the dizzy was not brand new but had a new cap and rotor.
Thank you for your help!

 

 

No **** sherlock haha, I know its inside the dizzy but i don't know what it looks like, But thank you anyways!

 

 

The picture didn't load untill now. I also said I assume its in the distributor, but oh well. Thanks
