VANESSA Posted January 10, 2011 Share Posted January 10, 2011 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 ?

jmurray01 Posted January 31, 2011 Share Posted January 31, 2011 One tip, never take your car to Kwik-Fit. Ever! Quote Link to comment Share on other sites More sharing options...
Mot tester and mechanic Posted February 10, 2011 Share Posted February 10, 2011 As Jmurray said, never use Kwik fit Ok lets start from scratch, first of all we need the values from the emissions report then we can advise further Quote Link to comment Share on other sites More sharing options...
jmurray01 Posted March 15, 2011 Share Posted March 15, 2011 Is the OP still interested in getting to the bottom of his emissions problems ? Quote Link to comment Share on other sites More sharing options...
mercerft Posted March 29, 2011 Share Posted March 29, 2011 Has the car got a induction kit? I had one on my old Focus and it put the emissions through the roof! Also, is the catalyst still in working order? If that's damaged then you will have emission problems. Other problems could be the car running too rich as well.

fishpond 47 Posted June 17, 2011 Share Posted June 17, 2011 Hi Zee, the three things the immisions check, the co, hc, and lamba, all relate to differant things, the easiest thing to understand is the lamba, this being the lanmba sensor thats in the exhaust system (yours is ok) the other two also relate to something, I know one relates to the cat converter, this is also part of the exhaust, !Removed! expensive, and usually the most common cause for the high readings, I will confirm tomorrow which is which as I've got an mot to do(at a good mot center ;) ) unless Mr mot tester and mechanic comes on tonight and puts us right.

fishpond 47 Posted June 18, 2011 Share Posted June 18, 2011 I can confirm it will be the cat convertor Quote Link to comment Share on other sites More sharing options...
btmaldon Posted June 18, 2011 Share Posted June 18, 2011 Try putting a bottle of cataclean in the tank before taking it in for an MOT. That will get the readings down and get you through the MOT. Quote Link to comment Share on other sites More sharing options...
Rhys-G Posted June 23, 2011 Share Posted June 23, 2011 When they are not looking and have your mate talking to the M.O.T guy, quickly take the tool out the exhaust and blow into the tool. Works a treat, well did on my 106 :D lol Quote Link to comment Share on other sites More sharing options...
FordDriver007 Posted July 21, 2011 Share Posted July 21, 2011 Hi, I had the same kind of problem when i took mine in, I got some stuff to clean out the cat, it worked a treat.
