    I have a 2006 GT Mustang. I love the car but it has some hesitation to it lately. I was on the freeway racing and I downshifted from 5th to 3rd and it didn't want to go.

  8. Weak Acceleration

    V6 Talk
    I have a 2002 V6. Most of the time when I accelerate, it takes a while to get some speed.

When I brake to a stop, my RPM's go down under 1K, and it shakes a little like it...
