2011 GMC Terrain sputtering and sometimes a hesitation on acceleration
My 2011 GMC Terrain has 96,000 miles. I get regular oil changes and use
recommended gasoline brands only Lately my car has been doing a "sputter"
when turning the car off. Also sometimes there is a lag upon acceleration. I
went to get a tune up but was given the 100,000 mile response and told to bring
back closer to the 100,00 miles. What can this issue be?
