I'm curious to know why after fixing vacuum leaks, my car still hangs when coming to a stop, then idles fine when stopped. It also doesn't do this all the time, but only on some occasions. It can do this one time and when I start the car up the next time it runs perfect. Or it can hang just for a couple of times then goes back to perfect idling when I'm just driving down the road. It can run perfect then after I shut it down and start it back up, it's hanging until the next time I stop and kill the car.
Any suggestions? is it somehow still reading past vacuum issues? and I need to clear the history somehow?
It's a 98 C5 6 speed.
