Hello, first of all, I am new and I hope you can help me with the issue I have with my Nissan Almera, a few days ago I went on the check Engine on the board and the car takes in Ecender, it feels very slow Tests while the engine remains the MAP sensor connector and my car is turned off, I think it is fine, if I remove the acceleration body connector stop working (accelerate) I think it is fine, and by removing the crankshaft position sensors, the fault follows the fault does not present anything different when they are connected, they believe that they are the two position of the crankshaft, finally the mechanic did not want to do these tests and it is waiting But a lot of money is made.

Thanks for your answer but you have to buy the manual.

You will have to see a friend, because the flow if you can give a corduroy of acceleration by not curing the air that enters and is low all the time, it does not fail to fail, not letting the vehicle start.
