Hesitent
 

Yesterday while i was on the interstate doing about 85 i had to slow down due to someone in front of me, i didn't touch the brakes, just let off the gas, when i did my car felt like it was hesitating to idle down,kinda of a sputtering, but when i touched th egas it was fine, it only did it for a little while , when my foot was not on the gas,. Any suggestions?
