I think I already know the solution to this but I dont want to replace the fuel filter or pump in the sub zero weather. Anyway, I have a 2000 v6 atx with 40,000 miles on it. Just the other day I went to pass someone and the car didnt want to go. It hessitated really bad until I let off the gas alittle. First thing I tried was some higher octane gas. This helped alittle but the hessitation was still there. So seeing as how it has been insanly cold outside I tried some gas line anti-freeze. Also seemed to help but it may just be in my head. The problem is still there. To my knowledge the filter and pump have never been replaced. Like I said I think I know what I need to do but I was hoping someone here may have some suggestions to hold me over till nicer weather.
