Something I noticed a month or so ago, after getting caught in heavy traffic for a couple of hours going into Boston, in my 2003 Murano with about 115000.
When cold, or from the house, the car is responsive and powerful as it should be. But after it sits in heavy traffic for a while, the engine does not respond to small inputs of the gas pedal. It is almost like it hesitates.
If the car is fairly cool, and still close to home, if in traffic, and we creep forward, the usual is to give it a little gas, and the car creeps forward.
Once the car gets hot (but not too hot, all gauges good) the same input in on the gas pedal gets no reaction. I have to push the pedal nearly to the floor before the engine responds. Then, it wants to jump into full speed, because of the position of the accelerator.
Since I believe I am driving by wire here, my first thought was to the computer, but I am wondering if there may be solution in the exhaust.
Any ideas? Does this sound familiar to something you may have dealt with?
