Cluster Gauges Sweep on Start

Cold here - Does this mean battery is starting to go or something else??? Cranks fast and starts immediately.

The PCM reset itself. You probably took the battery terminal off for a little while. Nothing to worry about.

Anytime they have swept for me is after the battery has been disconnected.

Mine does it every once in a while. Im pretty sure its because of my battery. It was never disconnected though when it does it.

Newstangman: I think your battery is going. I had the same issue, with my 99GT.

Car bought new 2 years ago and battery terminals have never been taken off. Car has never been back to Dealer - I do oil changes myself. Car just turned 8,000 miles. Still under warranty. Seems too soon for batery to be going bad, but anything's possible. If I shut car off and re-start immediately, gauges behave normally. Car is used almost every day, terminals are clean and as previously stated, cranks quickly and starts immediately.

Well, got back from a long ride and the Battery "eye" was green. I opened the "sealed battery" and added 2 cups of distilled water to bring level to the "split rings". After adding the water, the eye went to "red." I ran the engine for 10 minutes - still red. I hooked a trickle charger up for a few hours - still red. Any thoughts???

Battery eye back to "green" and gauges no longer sweep and function perfectly. Looks like all the battery needed was some distilled water to bring level to the split rings. Wonder how many batteries are replaced without checking the fluid level in these "sealed" batteries?
