volvo s60 t5 2002 not revving/driving above 2000 rpm
 

hi everyone,
i have a 2002 s60 t5 and for some reason it has decided to not play ball.
i drove my son to rugby this morning and car was revving and driving fine but after his 2hr session i started the car up but it will not rev or drive above 2000 rpm.
has anyone had this happen or know what the likely cause is please.

update. went to the shops 2/3hrs later and drives/revs fine. engine management service up on dash. after shopping start car and dash is clear of all warnings
