04 CTS 3.6 Throttle losing it's mind
84000 miles, My daughter was driving along the highway and she said it went to idle like she took her foot off pedal, she restarted the car and it was fine, this happend twice that day. it's been 2 months , now wife gets in it hits the start and it reves way up a couple times CEL comes on then it surges and bucks it way home. I slapped a scaner on it ,p2176,p0121,p0507. They all cleared . The throttle body and harness were replaced 2 years ago by dealer. Thanks for any help.
