Idle Problems

Just when i thought i had the truck sorted and was running reallt well, this is the problem i have now .
Sometimes when i shift from park to a gear be it forward or reverse the idle speeds up then comes down slowly.
Also as it is summer down here when i use the air con the idle speeds up and does not come down.
5.0 EFI V8 and AOD trans.
No codes from the reader and new motorcraft tps switch.
Thanks in advance.
