My throttle return spring must have weakened a little the last couple of drives as every now and then the rpm would be higher than usual when at a stop and wouldnt go back down to a normal unless I gave it a quick rev. At first it seemed like a TPS or stuck butterfly issue but after a closer look and hooking up the laptop to the Haltech to check the TPS calibration we found it was just a weak throttle return spring not closing the throttle body at its fullest when gradually lifting off the accelerator pedal. This weekend I'm gonna take off the throttle link and give the spring one more revolution to make sure she's got some kickback lol
