As title says it faintly flickers at the same time my tach gauge and speedo jump around. Voltage meter is where it's always at so it's not lower than normal. Just curious what could be causing this

 

Someone else said the cluster might be bad? Would this affect the car at all? Other than not knowing speed fuel etc

 

Crankshaft position sensor?

 

I think it's the alt... I just bought an escalade alt and new connector cuz mine is pretty corroded, I'm gonna knock this **** out tomorrow so we'll see if its gonna fix it lol

 

did that fix it?

 

My 98 TA is having the exact same problem and i also just put in the escalade alternator. It seems like it does it when i let off the throttle, but it doesn't always happen. If i bring the RPMs up it goes away. I checked all the grounds and they're solid. Did this fix it?
