Hi! I am new here, and I bring with my new-ness a problem. I just purchased a 1998 mustang, 6 cylinder, and I drive it down the road for say, 10-20 minutes, and it starts to act like it isn't getting fuel. It is real sluggish, and it has no power at all... i took it back to the dealer and their mechanic said it was the fuel filter, which he changed, and yet it still does the same thing. So, I am wondering if anyone has had simliar issues, and can maybe tell me which sensor it MIGHT be? any help would be appreciated, thank you!

 

Bad pump or bad gas?

 

dirty Mass air flow meter?
