New engine code after repair?

took durango to dealer and had the stabilizer rod removed and replaced they told me that it was hard getting the old part off. after driving for 5 minutes the durango acted like it wasnt getting fuel/ wouldnt speed up right,high rpm, when i got home i checked the engine code and it reads p1756. the car was running fine before i had it in the shop/ besides the stabilizer rod being screwed up. so now im wondering if it is possible that the shop some how caused this. would it be possible? by the way...thx dodge man for answering my other postings!
