Problems with Golf A31.8

Hello everyone I have a problem with my car a golf A3 1.8 it turns out that when I start it well and everything but when accelerating it between 1000 and 2000 rpm it makes the injection cuts and when accelerating it to more than 2000 it takes away the fault that does so for a few seconds later I accelerate it in that range and does not present the failure itself is presented when it is started and in the scanner nothing can be ? Will my gas pump or the computer be? I hope you can say to me of my doubt

Normally that type of failure is presented by the TPS sensor (acceleration) but if you do not present the failure at another time you can have a problem with the temperature sensor

Well, the truth is already checked and the tps were changed to another although the one who got used is used and the same temperature already changed it as 3 times something else that I have detected is that as the car had a good time it detects that my gas pump Now do it at normal temperature, you leave it 10 or 20 min, you try to start and take something else that is detected is that the spark plugs come out black and with a strong smell of gasoline that something else would you can advise me to check? greetings
