Mirez Posted February 2, 2010 Report Posted February 2, 2010 Clear them, drive for a week and then scan again. Since you havn't said you have a problem with the car its quite likely they are old codes left over from a previous repair/problem. Quote

My MPG seems to have dropped from 40 to 25 though, thought it might be something to do with the injectors? Seem to have an issue with acceleration but think i have pinned that to the air flow sensor due to unplugging it has no effect, so have brought a new one. CheersRob Quote

If the ECU isn't able to work out the correct air intake then it can't mix the fuel correctly :) Quote
Stoneblade Posted February 2, 2010 Author Report Posted February 2, 2010 Thanks Mirez, I will reset the faults and put in the new air flow and see how it goes, will probably be back with more questions lol thanks for your help already. Rob Quote
