I have a 92 -960 with 288K , the car is almost ready for my daughters college debute in August it rides like a dream with a few exceptions 1) when coming to a stop it shutters as if stalling out , does not do it every time but is increasing in frequency , 2) I notice when i accelerate the AC does not blow , once speed levels out Ac blows normal , is this a problem that is associated or 2 different problems , and any suggestions on repairs ?

Thanks
Scott
