Mileage is 91687
The diagnostic code initially shown pointed to an issue with the fuel pump solonoid which has been replaced. No further codes have ever appeared. Three fuel jet nosels have been replaced after work done to fit a reconditioned jet including nosel made no difference. The jets have been checked twice, once when replacing with a reconditioned jet did not work and once following the other three jets being given new nozzles. No codes have come up since then. The car is in good repair and had a full service in February, there was a problem with the power steering but this was sorted in February. Hopes this proves useful.
Sorry forgot to mention. No dashboard fault lights come up.
The misfiring/juddering only happens when the engine is stone cold for about ten to 15 minutes after the engine has warmed up all is fine until the next time the engine is stone cold.
