Lunging or hopping???
I have a 2007 Jeep Compass 2.4L with 4wd and lately, once the car gets warm (not necessarily operating temperature either), it seems to lunge or hop upon acceleration from stop or close to stop. For instance, if I slow down to turn on another street or if I come to a stop sign once I get some speed up it seems to cease (it only occurs between 0 and approximately 20 mph). It doesn't do it once I take my foot off the accelerator, but as soon as I begin to accelerate again, it starts again. I can't tell if its fuel related or transmission related or neither. No codes are present. Any help would be greatly appreciated. Thanks.
