Mot Failure On Emissions

10 January 2011 - 08:41 PM

I have a 2002 Ford Fiesta Zetec and it has failed its MOT on the Offside Rear Exhaust emissions carbon monoxide content after 2nd fast idle excessive. The garage I took it to said they could not diagnose the problem and advised I book it into a Ford garage for diagnosis. In the meantime I thought I would try my local Kwik fit to which they carried out the following tests and could not resolve the problem:
1. Changed air filter
2. Fuel Treatment added
3. Lamda ( sensor 2 ) ( Rear ) changed: Reversed readings from CO high to Lamda high / CO low
4.Repaired broken pipe ( vacuum) from fuel rail
5. Refit clips to air filter housing and induction piping
6. Run OBD diagnostic ( no errors stored)

They have written on their report:
Vacuum noise coming from right hand connection of fuel rail. Maybe allowing excess air into return system

Any suggestions to what could be the direct problem before I put it into a Ford garage ?
