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.

If you find the answer let me know I have a 2000 Maxima with the same
problem. Replaced the fuel filter, starter, had Nissan evaluate it and
they thought it was a sensor in the rear of the car. Reprogramed it.
No check engine light. No codes on scanner. Still doing it three
years later.

Only hesitates at cold start up once in the morning. It can sit up all
day after that and there is no problem till the next morning. Doesn't
make any difference whether it is 20 degrees or 100 degrees.

Have either of you cleaned your throttle body? Easy DIY job.
