When accelerating over 40-55 mph my 2008 equinox hesitates, sputtering until it gets over 55 mph. It is a quick hesitation but never the less causes loss of speed while getting on the freeway. We have tried working with the dealer and the basic oil, gas etc changes nothing helps and it is only getting worse. This has been going on for many many months.
