i have had a 98 sunfire since new and always had this problem when the battery was low on juice or mainly when the little wire that grounds to the battery holder plate , the little wire that comes off the big negetive battery cable , this conection would get all corroded and thats when the dash lights go crazy speedometer going up and down like its possesed , clean up that connection , use petrolium jelly when you connect it back up .
