Have my sister-in-laws Fiat Punto ELX , Y reg , with no power . Revs ok but when driving doesn't have any power . The car has just had a service last week and she has been driving fine untill yesterday , on a long trip and the power just died with the car going no faster than 30 . No warning lights on. Any bright ideas ? AA recovered the vehicle and thought it might be the catalytic converter .
Thanks
Ken

The O.P. says the engine revs OK, which would suggest the exhaust is not choked. Look for loose or split air hoses and trunking first.
