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 |

The answer is "no" unless you ask... Group: Members Posts: 1,192 Joined: 21-November 15 From: White Plains New York Member No.: 19,387 Region Association: North East States

Start with the basics. Ignition timing, vacuum leaks, visual inspection etc... High CO is a result of rich running condition. (too much fuel / not enough air). Could be caused by a few things, some of which may require diagnostic equipment. (DVOM, gas analyzer, Air fuel ratio sensor) May be something simple like clogged air filter, or 1-2 clicks on the control unit. After inspecting the basics, I would start with the DVOM and test cyl head temp sensor, TP sensor and fuel pressure. These are easy places to begin with. I'm sure you will get some good advice here.
