My car is bogging down in all 5 gears after driving it for over 10 - 15 minutes. It doesn't do it when I first drive the car. It seems like it is not getting enough gas but if I floor it, it will go . I just had a tune up, new spark plugs, wires and fuel filter and thought that would correct the problem but it didn't.
I store the car for the winter with gas in it and have never had a problem until this year. I added Stab-il to the gas tank because I thought I had bad gas. So far that hasn't corrected the problem. Any suggestions?? Thank you.
