Lately I've noticed that my Speedo is a little sluggish. For example it takes like 3 or 4 seconds for it to jump to the correct speed from 0 (zero). Then I notice upon stopping that it take about 3 to 4 second for it to show a speed of 0 (zero). The HUD and Speedo both behave the same way. Also, I notice that the guages are all a bit noisey. When I start the car w/ the radio off I can hear the mechanism as the needles do their little dance. Not sure if thats normal or may be part of the overall issue. Thanks.

I can hear my gauges "sweep" on startup also... Pat

my spedometer does something similar, its almost as if it doesnt register 0-4mph, then i hit 3or 4 or so and it jumps up, same when stopping, it stays around 3mph for a second, then drops to zero

Mine does the same thing... it'* odd. Try this one, while driving turn the key to "start." All gauges will freeze at their current position.

Well, that makes me feel better. At least I don't have another repair to worry about.

Please...do not try this...this will engage your starter and possibly damage your flywheel and or starter.

(Unless I'm reading this wrong Dan?)

The 2000+ vehicles will not engage the starter while the car is running. But i would still not recommend ANYONE trying this EVER, its just not a good idea

Don't worry, I took it only as a joke...which I'm pretty sure it was.

Actually, I don't think Dan posted it as a joke. I believe he knows about the starter not engaging and suggested it as a test. I didn't know about the started and wanted to err on the side of caution.

Might be a valid test...
Dan....is that what you are hoping to find?

it does not hurt anything at all on 2000+ vehicles. The starting procedure on the last generation of Bonneville is 100% PCM controlled. The PCM cranks the engine until it senses it is started, even if the driver already let go of the key. once you flick the key to start it'* all automated from there. Anyways, by turning it to "start" while driving the only thing you're doing is having the PCM only run systems that will work while the engine is cranking, such as ignition. The climate control, radio, and gauges will fall dead. It doesn't hurt anything at all, trust me on that.

EDIT: The reason I know about this is because I would at times get errors such as the ABS/ TRAC OFF message because of a bad wheel sensor/bearing. If I turned it to start while driving, everything was reset, thus getting rid of the error for a while. It can be usefull to do this.... for some things. It'* a heck of a lot easier than pulling over, shutting the car off, then restarting. If you wish not to try it, you don't have to, it'* just convenient if you ever need to reset a system on the car, while driving.
