My truck has stalled a couple times at low idle in the past. The idle was not at a consistant rpm. I changed the battery 2 days ago. Now the idle fluctuates between 200 and 600 rpms constantly. When I drive it, it is fine. When I come to a stop and the rmps drop quick the truck stalls every time. Starts right back up.

In addition. The tach, speedometer, fuel gauge and voltmeter all peg in the negative direction and bounce or vibrate for about 5 seconds when starting the vehicle, then all gauge resume normal operations.
