High idle in drive

01 SILVY 148K MILES 5.3L truck runs good but after warm up on a warm day the truck will idle at 1k rpm when in drive.When I am in coasting to a stop light or trying to coast with traffic it will have a high idle to where I need to allways apply the brakes.I have checked for vacum leaks allso took off TB and cleaned it allso took out the IAC and cleaned it.Has not thrown a check eng. code since I have had it 05. What else can I check.
