So over the course of about the last 3 months there has been construction going on at the entrance to my subdivision and there is a pretty bumpy patch of road i need to go over to get out. everytime i go over this series of bumps my car seems to stumble, run rough like it has a slight miss. After maybe 10-15 sec of driving on smooth road again the car clears up and drives fine. It only happens on this peticular set of bumps. I have checked everything that I could think of that may come loose and everything is were it should be and its all tight. is there anything that may be jolted that im not thinking of that could cause a momentary stumble? Otherwise the car runs hard and strong. its just wierd that it only happens on this one set of bumps? I guess its hitting something just right, but I dont know what, any ideas?
