I feel my auto 5.0 GT lost some oomph
I am a fully non technical guy to begin with, I just love my Mustang.
I have driven it daily for the last 4 years and have put over 68.000 miles on it.
And I have the feeling that it's lost some oomph, I feel it when I start it, before when I put it into D, I had to brake firmly or the car would start advancing inmediately, on a steep uphill it'd move also, now it goes backwards in a steep uphill on d if I don't push the throttle.
My mechanic says the clutch is in perfect condition and he says it's me, that have gotten too comfortable with the huge torque and power it has, but the uphill thing is not subjective.
Consumption remains very similar, haven't felt any difference.
I also have the feeling it's harder for the car to rev up, at first, when I stepped hard on the throttle I had the feeling it was more a projectile than a car, now it takes some time to gain speed...
is it the clutch?
Is it that the engine is "worn out"? I really doubt it, for 68.000 miles (and never been tracked) is nothing for such a huge engine...
Thanks in advance for your expert comments.
