Cant find what the prob is

Good day I have a nissan sentra 2007 2.0 cylinder…recently I have been having trouble starting the car. Everytime i the car is started for the first time for the day the rmp gage fluctuates.At times it shuts down.  However onces it starts it doesnt stall out on the road yet. Every mecanic that checked the car said it can be the cam sensor it has been replaced twice so far and still having the same problem. My car has aprox 7200 km on it.  Can you help me pls..

  1. First thing to do would be to scan the computer for codes and then post them back here. You ca have this done at Autozone for free or if you already know the codes… Post Them. Fluctuation of rpms could be a vacuum leak also.
