what would cause a bouncing tach needle??

[1994 Integra]

My tach needle bounces all over the place. Not actually engine speed. just the tach in the cluster itself. and everyday. it runs worse and worse. I have new cap n rotor. wires. icm. coil. im thinking main relay but idk please help!!

Clean the iacv

Clean the iacv

his car isnt doing it at idle.

Its the tach signal being jacked up somewhere. Clean your dizzy connections and check the ground on the thermostat housing. that controls the dizzy. Tighten it up or you will have major problems

ok i will tighten that ground up when i get home!!

D could this be caused by the vss too?

the vss has nothing to do with RPM's as far as I'm aware. How can a sensor that measures the speed at the transmission know what rate the motor is turning?

funny thing is on my way home tonight the speedo stopped working. fml... but i took that ground off cleaned it. it it dies every 5 mins. tach needle still bounceing.

So it's your rpm needle that's bouncing and not your mph needle? Just wanted to make sure.

take your distributor cap off
carefully take the spade connectors off the terminals
crimp them tighter
re-install connectors onto the terminals
put cap back on distributor

problem solved


bet you 25$
