I just had alternator replaced about a month ago and front wheel bearing done cost 586.00. Now seems like after I drive awhile when I come to a stop car seems like it's going to stall and then seems fine?

hi, mostlikey you have an idle air control vavle problem, its a little valve that is in a bore on the throttle body, it controls idle speed when coming to a stop or turning corners, basically when you take your foot off the gas pedal this comes into play and allows just enough air in to keep the car running. along with that you may want to do a thorough throttle body cleaning, and get rid of the carbon buildup in the throttle body . you would be surprised at the the problems carbon will cause with idleing ,stumbling on take off, etc.
