The rpm seems to hang longer when I clutch in to upshift or when coming to a stop.

There is also a very noticeable bog when accelerating between 2000rpm and 3000rpm in all gears where the power just falls flat.

I called the shop this morning to ask wtf they did to my car and was assured they didn't touch anything under the hood. I have heard that some alignment shops disconnect the battery during service which might cause some of my problems temporarily. Its been about 40 miles though and these issues haven't improved at all.. Still high idle, rev hanging and low rpm bog. Ideas?

What idle speeds do you all see with a/c on and off?
