Have you got the check engine light on?
Does it rev in neutral?
It needs to go to a garage or if you gave AA or RAC cover see if they can sort it or tow it to a garage.

There were two major problems with that car, a leak in the coolant system & the ignition cylinder falling apart, neither would cause your problem. Take it to a dealer.
