Mazda 6 Motor 3.0

I have my mazda 6, engine 3.0, the engine was repaired and at the time of assembling, the mitchel was proceeded, and the procedure was raised and I did not start, it takes it to another mechanic and in one day it could start it because he said that the information of the mitchel, does not serve to put in time the engine of the mazda 6 cylinders in V, now that I put it in time it marks me one of them is 2 codes And the other is from the CAM, the truth is that it seems to me that the time is, because at 2500rpm already 3000 rpm, it makes a fuel cut and begins to do as it had a garbage in the fuel passage, but above the 3000 rpm, it is established again if someone could help me to know what to do I appreciate them.

The first thing is to check the sensor itself to see if it is in good condition if it is necessary to check the cable branch, usually and here in Chile the CAM bus is the wiring of the vehicle, the injection cut that the vehicle performs if you can go hand in hand with this failure, but you would make sure that everything is well connected and that you do not have false air inputs, if you have a Czech flow. of the same and the body of the admission to rule out onbstructions for dirt.

Thanks Kikiemec, I will make these observations you write to me and thanks again
