im new to the site but basically im having a problem i cant solve my tach and speedo go crazy while im driving when i wop motor buckles installed a brand new dizzy still acts up im thinking its the vss people telling me could be grounds any help please

 

sounds like speed sensor, my buddies Prelude had the same issue

 

thats what im thinking im looking around for one hopefully i find one soon and fixes the problem

 

when the tach goes jumping around, the ignitor in your dizzy is failing. buy oem ignitors..theyre a bit pricey though

check your grounds...should read the same as battery terminals

 

realy cus i just bought a brand new dizzy put it in swapped clusters swapped speed sensors my buddy loaned me but it was from a d series will it still work i checked every sensor on the vehicle still nothing ..?

 

i also upgraded to 4 gauge ground wires even added one to the throttle body

 

Check the ground on the transmission side. I had a bad connection there, it caused my speedo and temp gauge to go crazy. It also burned out my main relay.

 

Ill check that one a buddy of mine told me it could also be a bad Tps ..?

 

Normally this is an igniter issue. Since you did swap in an entirely new Dizzy, I would say you SHOULD be ok. For giggles, have you also checked plugs and wires?

I would check and then double check your ground on the thermostat housing, clean it and reinstall it.
