Hi-Haven't been around for a while, scrolled sites-I just started same thing today! I'm blaming it on a half tank of gas at a station I never go to-I was fine until shortly after that. I left tank at 1/2 full and dumped in a bottle of injector cleaner-stopped hard,swung around corners to stir it up a few times (didn't want to dilute w/ more gas)
I've put on 15 miles and haven't noticed a change yet.
Maybe we have the same problem? Have you tried fuel additives? How are your spark plugs, wires etc.? Fuel filter? These are all things I should attend to-NO TIME (!)
Keep us posted-Good luck!
