crazy idle after door slamming

OK I replaced my TPS it's at 54 Volt's.
..In the am I can go out an start the car an it idles at 850-900rpms after putting it in gear about 780rpms.. Although after a drive I put the car back in park or neutral it likes to jump to around 1200 rpms ...I can cut it off for like 30 sec. An start her back up ..An it tries to idle at 800 ..I noticed the other day as my girlfriend closed the door the TAC jumped a couple hundred rmps an stayed there ..Then last night I slammed the driver doors an saw it jump so..I'm looking for new insight on this

Connections, specifically at the ECM, are suspect. The block of orange wires (AUX/IGN power) are also worth looking into.
