Thanks for getting back to me and explaining. The Emissions this year are the following :-
fast idle : cO = 3.88 , HC = 455 , Lambda = 0.890
Second Fast idle : CO = 6.25 , HC = 704 , Lambda = 0.826
Natural Idle : CO = 0.99
I will check what you have suggested with plugs etc, the car starts perfectly and never misfires in fact it drives very well, im not sure from the readings above how serious it is or whether a service will bring the readings down again like last year?
Thanks for the reply again, ok what I will do is do the service oil and plugs. When you say HEGO I am assuming that this is the Lambda sensor pre cat (this car has only 1 sensor) I did replace it last year and the car went through the MOT , I can test or replace it perhaps it went wrong?
I don't think its major its just a pain all these emissions! I do have a ODBC2 connector so was wondering if any software can check emissions...will this also say if the sensor has failed?
Thanks again Sean much appreciated
