Just a minor annoying thing that's been going on for the past few weeks with my car:

In fourth and fifth gear anywhere between 2000 and 2700 rpm and just barely touching the gas to about 20% of max throttle the car seems to stutter or hesitate almost like I'm continuously tapping and releasing the gas - it's not a very harsh feel, just kind of annoying. If I shift or give it more gas the problem disappears for a while. Also, it isn't constant when those conditions are present. In fact, I really can't seem to predict when it will happen other than those conditions have to be present for there to be the possibility. Any ideas of what it could be?

 

sounds like your CAT is holding you back.
