I have a 1998 Olds Intrigue with the 3800 Motor. 125,000 miles. Haven't had a bit of trouble with it until now. Car was running fine when we parked it one night, got up next morning to go to work and it is missing, cutting out, and bucking under acceleration. Once you get it up to speed and set the cruise it will run fine until you get to a hill or something where it comes under load again and then it cuts out. Anyone have any clue on what I should look for???
