hi there, i need some help, i have a 99 buick regal with about 60k miles on it and I am having a problem with rough idle and the check engine light coming on. when I read the fault it told me I was having a misfire in cylinder #2. have been to dealer and local shops and alhtough they like to take my money, no one has been able to solve the problem. it is especally noticable if you lift up lightly on the brake. really feels rough. if you give it any gas it runs smooth. also heres what I have done so far. fuel injector cleaner through the rails twice. new plugs, new wires , coil pack and ignition module, hi test gas and about 5 bottles of injection cleaner through the fuel tank.after the last time I got the car back, the check engine light stayed off for about 100 mile and now its back on again. any help anyone can give me will be greatly appreciated.
thanks Teddo
