I am a first generation owner of a Mustang. I traded up to a 2011 GT
premium convertible from a Honda Civic that served me well for 12 years.
I bought it used from a private party. It is an automatic. There are some upgrades: Roush suspension and cold air intake, Magna-flow x-pipe and exhaust. There was an SCT-3015 tune, but the previous owner took it out.
Anyway, on to my first question. I have noticed from time to time that there is a hesitation when I accelerate from a rolling stop. For example, I will not come to a complete stop; rather, I will slow down to ~5mph and then accelerate. At this time there is a hesitation and then it accelerates. It is not consistent however. It appears to happen when there is a slight downward slope in the road and I have yet to notice what the RMP is as I am decelerating (maybe that is a data point).
The reason why it concerns me is I know the previous owner had a tune and then removed it because he "did not like the way it drove." I have been reading of reported problems with the 2011 GT transmissions while other posts mention skip shift.
I have a year left on the power train warranty, and I am thinking I should at least take it into Ford to have my complaint documented. Reproducing the "problem" is a bit tricky as I said earlier since it is not consistent.
Any opinions, thoughts, peace of mind suggestions, or STFU noob would be appreciated.
