[bigaustin18]

i have a 1993 ford ranger 3.0v6 2wd it will run fine but when i decelerate the idle stays higher then normal and when i tap gas it wants to shut off sometimes it will shut off take a while to start back up. what could this be?? need help asap

Very likely the IAC valve is dirty/sticking or shot. Also could be a vacuum leak. The IAC won't generally throw a CEL but a vacuum leak eventually will (lean bank, etc).
