Thanks for the reply tabetha.

Sorry to be a pain, but I am not very knowledgeable on cars. How easy is it to get to the Mass Air Flow sensor, where is it located and do I need anything special to clean it ?

Can you also explain how to reset the ECU with the KAM fuse ? Is this not the same as disconnecting the battery and leaving it for a given period of time ?

Many thanks.
