   Has it been serviced recently? Was the timing belt changed?
   
   What state are the spark plugs in. Could be a dodgy lambda causing it to run rich.

   Change spark plugs & lambda sensor. Sounds like your lambda has gone to me which has caused it to run rich.
   
   That would be the black stuff all over your spark plugs

   Give it a good full service. Check the inlet manifold for any holes are gaps at any joints.
   
   Get a new cambelt on asap if you dont know when it was done last.

   I might also be worth checking all of the pipes/hoses from the petrol tank as well for any leaks especially the connector behind the inlet on the bulk head( If you look in the pic you'll see 2 faint red circles were they are under the bonnet).

   thanks guys, the lambd sensor is changed and am going the do the spark plugs to, was going to do the oil change but i have noisy tappets and need to do these before i do the oil change as it would be silly to change the oil first. i will also check the fuel lines too.
   thanks leigh

   Do you have any shite in your header tank or any creamy substance/ emulsified oil in you oil filler cap? or using water?
   
   Hope not but could be head gasket?

    when you set your tappets make sure engines been run for a bit and is warm, couldnt mine to stop tappeting for ages, it was ebcause I was setting them cold...

    I thought 3K revs was the ECU in protection mode?
    
    Tried disconnecting the battery overnight and resetting the ECU?
