the idle up when the car is hot -
Car was in for service and the next day it began to idle rough. I brought it back into the shop and they identified that the t valve had become cracked and was causing a vacuum leak. The mechanics denied any wrongdoing and so I took the car to another shop to repair the issue. Not saying that they broke it but their ice cold bedside manner didn't provide enough reassurance for me to keep shelling out perfectly good benjamins to suspect mechanics. lesson learned. -
