Hi, my versa is a 6 speed manual. Recently I have noticed that the car hesitates and bucks a little when I slow down in 2nd or 3rd gear. This happens when the car is warmed up. I also don't think that the clutch is slipping because the car does not rev/rpms do not increase when accelerating. I just hesitates for a second and then bucks forward. I do not have a check engine light on. Oil was changed a month ago and at that time the coolant was also changed. I have 135,000 miles.
