No acceleration in the car today Each time i tap the accelerator it revs from 2 to 4 but it doesnt speed up. Only drives around the 40-60 mark with momentum.

Any ideas of what could cause this?

Have you took the Handbrake off ??

Sometimes the simplest suggestions solve a major problem

Slipping clutch maybe.

as above or

Gone into safety mode (limp home mode) so you'll be running very low boost?

Maybe the ECU protecting the engine due to commpression loss

ah so when im driving in a gear and accelerate it may actually have slipped out thus driving along in neutral...damn how much is that going to cost?...

No, just slipping so not transfering the full power to the drivetrain. do the revs rise but the car doesn't accelerate or does it just feel down on power?

Is your car an auto?
If it is it could have(does have g/box fault).
If it is a man. it really sound like clutch slip, if you get to a clear road take the car to around 40 mph in third make sure your foot is off the clutch pedal and acc. hard if the revs really rise(both sound and rev. counter) and your road speed does not rise dramatically then the most likely reason is a worn clutch,this is reasonably inexpensive to correct.
Dramatic clunky noises (loud and vibration) could be a broken/damaged driveshaft/diff. problem but this is almost exclusively a problem on heavily modded cars. hth.

InvisibleMan

yes this is what happens. When you say reasonably inexpensive, whats the ballpark figure?

£7-900 quid, you may need the flywheel replacing (most people have this done at the same time) hence the expense.

Depends whether you can do the job(or know someone who can) the parts can cost from around £80/£300 depending on what model your car is and a half day(ish) labour in a garage,get someone who has done them before as thay are not difficult but there are a few parts in the job that experience really helps.
Where are you, unlikely but if you are local to me (SW Scotland), my local boy charges me £50/£250 fitting(he is a friend tho.)

Speak to David @ API and get an Exedy clutch from him

InvisibleMan

ok its an old sport and to me £700 doesnt sound inexpensive an not worth it for what it is. i need to get rid of it, any offers?....
