I have this problem that happens around 900 or 1000 rpm when I idle that my engine starts to to a weird jerking motion that kinda feels like a gurggle? And after I finally get going again and give it gas it kinda jerks 5 or so times the takes off when the gas finally hits burns or something. I don't have a warning light for it and I don't need another oil change for like 1000 miles so I'm really confused to what it could be. HELP
