This morning I took the car for the government road worthy test and it failed due to high CO emissions . (IMG:style_emoticons/default/headbang.gif)
The CO value measured at the tail pipe was 6,2% it need to be under 4,5% (not sure what the units are something they call CO/K value) If members have any advice on how to reduce the CO it would be appreciated, I have to fix it by the 9th of August otherwise I cant drive the car (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif) The engine is a 2l with 20556 PC´s and running D Jet Thanks in advance |

If all else fails, turn down the fuel pressure several PSI, will lean out the mixture for the test. Easy to do.
