make sure throttle position sensor was installed correctly... very easy to put in incorrectly. Start with sensor turned far right, then turn left till screws line up

I would pull it apart before byeing anything, may be a simple get in back on track

Taken??? how much did you spend???

go buy a cheap heat gun (harbor Freight $10 bux... open the trunk and warm up the areas where the studs are but take your time... there is thick 2 sided tape on top of trunk lid and you may be able to re- use it
