Engine/Transmission (1998.5 - 2002) Fast idle

[jughead]

Got in to my truck today drove to McDonald's and everything was fine. When I got back in and started it to leave it started idling at 1600 rpm. No check engine light and everything seems fine. Any ideas?

do APPS reset sequence and see if it calms down

Add you truck specs to sig, and check floor mats.
