I have a huge power loss problem with this car especially uphills, and when changing from third to fourth to fifth, it has no power, when I press the accelerator there is a sucking sound coming from the throttle body. I did a major service on this car in December.

A catalytic converter gets plugged up and restricts your exhaust. That will cause you to hear the air coming in but the restriction in the exhaust won't let enough out fast enough. You can check that with a back pressure test which a exhaust shop can perform. Also. Would be a good idea to check your computer for codes. Also wouldn't be a bad idea to check to make sure you have the correct fuel pressure.
