MY TEMPERATURE DASH INDICATOR MOVES EVER SO SLIGHT WHEN STOPPING OR DRIVING THE THICKNESS OF A PAPER MATCH?

What is your question?

I HAVE A NEW CAP ON RADIATOR, CHANGED FLUID DEXCOOL, NO LEAKS , YET THE TEMP GAUGE MOVES JUST SLIGHTLY AT TIMES ,NO LEAKS NO PROBLEMS, BUT MOST OF MY PASSED CARS THE TEMP STAYED PRETTY MUCH CENTERED?

How long has your 2003 Buick LeSabre had this problem?

MONTH OR MORE
