Acceleration problems Dodge Neon 2000

I have the problem that the engine has many acceleration changes simply accelerates a lot and so it is maintained, it is composed when I turn it off and turn it on but soon, it will be the same, will it be a heating problem? What happens is that the radiator fan did not enter and what I did was put it directly and remove the relief and fuse of the fan

I believe that you should check the water system and purge it, that it does not have air, the second check the operation of the temperature sensor.

Good I think you should check the TPS.

Czech that there are no broken empty hoses. See if disconnecting the MAF sensor the engine is better. If so clean the sensor with freo cleaner and very careful.

Well, apparently the problem was that the air filter was covered, when I remove it, I will improve it but I will continue trying it
