I am interested in the experience of others. I recently got a 2006 4-cyl limited and really love the car . One thing I've noticed however is somewhat erratic acceleration when I press on the gas, usually from a stationary position. Sometimes it's very responsive and just takes off, whereas on other occasions it seems like not much happens for a few seconds and then the car will almost surge forward. Obviously one wants to predict what the cars response will be and expect it to be reproducible. Have others noticed this or does this seem to ba a peculiarity of my car and deserve a service check. If so, any ideas...?
