Hello,
I have a Nissan Sentra 2001. When the car has not been driven for a while (say overnight or even a few hours, even now in the summer) the car starts fine, but then I have 30 to 45 seconds of some trembling and the throttle hesitates. I cannot accelerate even if I floor the gas pedal. After 30 to 45 seconds the car seems to run fine.
I have looked all over the net for clues but there seems to be a million possibilities. My mechanic said the the Oxygen Sensor voltage seems to be low, and that this may be the cause. However I do not want to change it and find out that the problem did not go away. Anyone ever experience this?
Thanks.
