Question type: Maintenance & Repair

My 98 v6 5-speed has an odd problem, it idles fine, but when it warms up and i
start to drive more aggressively, the RPMs drop extremely lowly and if i coast
in neutral itll drop to and stay at 1500 rpm until i come to a complete stop then
it will slowly come down to the 1000 idle.
