LRP 1)) coulddamage the catalytic converter.On vehicles with a catalytic converter, thefuel tank filler neck is of a narrow design sothat a dispensing pump for leaded fuelcannot be inserted.Damage to the catalytic converter or thevehicle may result if the following pointsare not observed:z Consult a workshop, such as yourVauxhall Authorised Repairer, as quicklyas possible in the event of misfiring,irregular engine running following a coldstart, a significant loss of engine poweror other unusual malfunctions whichmay indicate a fault in the ignitionsystem. If necessary, driving may becontinued for a short time at a low speedand with a low engine speed.Irregular engine running and a loss ofengine power when the ElectronicStability Programme (ESP® Plus 3) comesinto action are the result of operatingconditions and are therefore of nosignificance – see page 208.6Catalytic converter for petrol engines 203Catalytic converter for diesel engines 204Controlling exhaust emission.............. 205Exhaust gases ...................................... 206Maintenance ........................................ 2071) LRP = Lead Replacement Petrol.
