problems with my corolla

I am writing to you from Venezuela, my problem is the following, for a few days I present a problem with my fighting partner ... I have a corolla 95 known here as the baby camry, 1.8 GLI engine the 7AFE ... well the question is that walking on the street sudden Peeeeerooo entails when I try to roll it corcobea or drown (I don't know how they tell him in his country), he has no strength at all, he is not able to reach 4000 rpm, but there is something curious this only happens if the pedal flooring thoroughly, but if I do it very slowly the car if he reaches high rpm. Conclusion I have my rugged cart and there is no mechanic that with the cause (I have already brought several to review it), I hope they help me ..

Note: approximately one month ago I did service. This consists of:
Time or distribution strap change (original Toyota)
Tensioner Time
Cables of new spark plugs
New spark plugs
Motor air and gasoline filter
Pile or gasoline pump
Oil change and motor filter

I don't know if this influences something ... any opinion will be of great help ..

Look at my dear cheka the current towards the fuel pump makes this failure due to the lack of electric corner
review and tell us

Well, the pump changes it two days ago, as the current is measured.)
