I have had my 93 sts for 2 years. When I am cruising around 60 or so and let off the gas my car sometimes acts like it is going to quit. The only way to describe it is it coughs. lol and sometimes when I let off the gas it will stall. I have asked alot of people what they think. I was told that I am either running on 4-6-or 8 cylinders . I think it has something to do with it but don't know for sure. I may not be describing this very well but it is the best I can do. The computer always says systems ok. I just hate to take it to a dealer because they rape you in charges. If anyone has any ideas please write me at
perkydeb57@gmail. thank you and I do appreciate this.
