I have just acquired this car and did a tune up on the vehicle and the speedo bounces driving down the road and even worse on the back country roads. I am not throwing any error codes.

anyone have any ideas?

thanks in advance

I believe this topic has been covered, the speedo cable needs to be lubed with special, speedo cable lube.

I wonder though, wouldnt an 89 have a digital-analogue speedo (oxymoron, i know). My car has a digital speedo, but its an analogue needle. Maybe an intermittant speed sensor cable? County roads would make the situaton worse?

IF it has a VSS, then replace it. There is no fixing it if the it has an electronic speedo then this is the only thing aside from a a bad wire that can cause this.

what are the odds on the actual cluster going bad?

I dont have a speedo cable i have the vss/electric pick up

If it were the Speed Sensor, I would think the vehicles computer would bring that up as an error code seeing missed pulses. So, the guage would be a good place to start looking for an intermittent connection. Sounds like something is just loose or not making a constant connection.

On my car, the guage just "plugs" into the dash. Check the connector for firm fit, and no damaged pins.
