Mileage is 91687

Registration DY51EWF.


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.

Hello again -

Thank you for your reply.

Ok - with this engine, there is a known / common issue that causes poor / bad cold starting / running - as you describe.

This is to do with the valves in the engine - over time basically they close up - and cause the compression problems - hence when cold, the troubles you describe.

You need to have the camshaft / valve clearances set up to the settings they should be... that should clear / sort this for you.

The settings that they need to be reset to are :
0,40+/-0,05 mm (cold engine).

Any garage can do this for you - its about an hours labour or so.

Let me know if you need anything else -

Kind Rgds - MIKE.
