Why does my car 'jump' when I accelerate?

Question

I have a Vauxhall Corsa 1.0i (53) It has recently started 'jumping' when I accelerate. My Grandad would have said it has Kangaroo juice in it!! It feels like a blockage or loss of power. Does anyone know why it is doing this? Is there anything I can do myself to establish/correct the problem without having to spend hundreds of pounds taking it to a garage?! Any help/suggestions would be very much appreciated.

Answer 1

It isn't a serious problem. You may have a blocked intake pipe, a slightly imperfectly aligned clutch cable (if it is a cable one) or it may have a minor problem with the injection system. This will eventually become an issue but you'll get away with using high-octane fuel for a while (super-unleaded). This will give it the extra power it needs to accelerate smoothly.

Answer 2

If you are still striving to improve you are vertical and you are looking to get your hands over the rim, set Vert Shock to the test, a course that you will believe it is here https://tr.im/4QSrJ  and provide it a try, you'll be surprised of how fast you can be an animal hopper if you train the proper way.
The program will not allow you to leap tens and thousands of times because Vert Shock was produced and employed by actual elite level basketball players.
When it comes down seriously to it, if you really want to leap higher, you just discovered the most effective program on earth to do so. Any way might merely be a spend of time.

Answer 3

Has it just started happening since the weather started to get cold or when your engine is cold? You cant ask to much from your engine when its cold and give it a mile or 2 to let it warm up a bit.if its doing it at normal operating temperature then you could be putting the acceleration a bit to fast.
Another thing it could well be and i dont know if corsa's have it but it could be the traction control. it cuts power to the engine when you put your foot down. happens with my car a lot and is a pain.

Answer 4

Tech 2 test a vauxhall. On a 53 plate possible still under warrenty if it was a late 53? Sounds like throttle body/egr valve to me and experience of working at vauxhall.

Answer 6

Take your car down to your local vauxhall dealer, they will do what is called a 'tech 2' test, this will give any information of any sensor on your vehicle that is reading outside its parameters. It could be a number of things, such as egr valve, idle air control valve, air mass meter, etc..

Answer 7

I FOUND THE ANSWER - also asked in Yahoo Questions. They have a Corsa that was doing the same thing when driving.

The answer was to replace the Spark Plugs and Oil Filter.

Hope this helps!

Answer 8

Try and work on your clutch control a bit more. Work the acceleator and clutch like a see saw. When the clutch it flat down the accceleator should be up and the same when the clutch it halway down (or up) the accelerator should be about halfway.
Hope this helps

Answer 9

Get yourself a Haynes manual. They are available in halfords and check your spark plugs. I have done mine and they are easy enough to do.
It costs money taking a car to a mechanic so the more you do for yourself the better, but I would advise taking it in for a full service. this should be done once a year or every so many miles. (can't remember how many, it depends on the age of the car)

Answer 10

It could be as severe as a clutch or transmission problem, but start by looking at your spark plugs. Drity plugs mean you lose the power in your engine, and it will usually lurch. Check our the plugs first, then maybe have your tarnsmission looked at. A gear my be slipping.
