Finally put the car for MOT.

 

the engine was last used properly December 08. ive taken the car out once for a 40 minute drive since.

 

heres the emissions results.....

 

how can i resolve this?

 

 

o2 sensors are gone?

 

or isit the fact that its been off the road for ages, and had a few boost leaks since back together (smoked, but now are all sorted) and just needs a good hard drive to clean itself?

read that removing a vacuum pipe from the balance bar reduces it a little,

 

but how much is that going to effect it?

 

im gonna have to give the car a bit of hell i think then take it to the test

looks like its almost twice over! deffo sort those o2 sensors have heard the pipe of the balance bar works but never tried it myself.

ok.

 

waiting for others who have used to pipe trick to advise what reading they had before they removed the pipe.

 

 

as its running rich, this will obviously effect my petrol consumption, but much or not? (dont know how picky that reading of 6% effects the running of the car

has the car got cats or are they gone?

any good.

chec,k those oxy sensors /if faulty you will run rich, pipe off will only cost you in the long run [m p g ]

car is de-catted.

 

how can i test the lambda/o2 sensors then? multimeter?

 

 

what happens if i disconnect them (connections in the engine bay)

 

 

so will removing a vacuum pipe will bring it down, but that much??
