my car vauxal coursa 1.4 dont no why it doesnt pick up speed ?

If you're in top and put your foot down, is it that the engine speeds up but the car doesn't?

As Good Luck says, that's classic clutch wear and time for a new clutch.

You can find out whether your engine has a timing belt or a timing chain. Corsas (and Coursas :-) ) have both, which one they have depending on the model and year.

Once you know (or no) please be aware: timing belts need replacing regularly. Skip that and it can be goodbye engine if the old belt breaks.

This site may help with questions in general for the Vauxhall (or vauxal) Corsa

Do please try to post in English though. Using "Textspeak" makes understanding what you are actually trying to say quite difficult.

In my experience your clutch needs replacing.

Going up hill is harder work than running on the level.
A dodgy clutch will show up first when going up hill.
If the engine revs in response to what your foot says but the car doesn't respond - it's the clutch.

Good Luck...
