The fact that the fault occurs at idle or when accelerating, and is worse
when the engine is warmed up, tends to confirm crankshaft sensor failure.
It appears to be a common fault with this engine.

To replace it is as much work as changing the cambelt, and unless the
belt has been replaced very recently it would be folly to put the old one
back on.

You might want to have a look here:

Perhaps it's easier to change the car!
