well i had the light come on the other day lol first thaught was bloody injectors, after taking the throttle body off and cleaningh it up then taking TPS etc off and cleaning them the light dissapears, just thaugh id put this up incase anybody else gets it .
before i did anything i removed all the electrical components then used brake and clutch cleaner to kill all the grease and oil then took a bowl of soapy water and scrubbed it then got the dremil out used the grit paper roll and ground the inside out to a debth of 2mm all way round to take that hump out of the centre and then cleaned it off and fitted it.
