   Disconnect battery for an hour.
   
   When you change a sensor it's best to reset the ECU to learn itself again with a new sensor

   Well ill try leaving it for a hour, A man down the road works for the AA so he will reset it later when he comes to look at the car.
   
   Thing is though hes not coming till later and i cant drive it with it revving like that dont evan want it to be runnning!
   
   It says on the instructions i might need to drive at a certain speed for it to realise where the correct something is?
   Any ideas on that one or is ressetting the ecu the best idea?

   different ECUs off different cars work differently.
   
   heard different ways such as.
   
   turn the key on n off the ignition 9 times
   
   drive the car 9miles ish or 5 minutes

    Ignition On, Wait 30s, Ignition Off, Ignition On, Wait 30s, Ignition Off, Ignition On, Wait 30s, Ignition Off, Ignition On, Enter Immobiliser Code - Start!
