Ok, I have changed the fuel filter last week The problem was there b4 and after.I have just changed the coil pack and ignition module(which was expensive) Just test drove the buick and no change. I don't have a mechanical pressure tester but the fuel has good flow and squirted pretty good when the fuel filter was changed. Is there any kind of sending unit that might be bad? I heard that some additives can hurt some sensors but don't know which ones or where they are?
question: I have done what was told about my Buick which has not helped except eliminate the extra money in my wallet. If answer to my question is not correct is there another answer. Its said if I am unhappy I can have a refund? ? ?My car still coughs and stutters while warming up. While cold its great and when warmed up all the way its great. New plugs, new wires, new fuel filter, new coil pack, new ignition module
