does anyone knw why my turbo2000 has just started over fueling and running rich on gauges because took it for its mot last week and failed on emission it has not a cat on it so already aware of it and its smells of petrol wen car stops and turned off plz help

 

Failed Lambda sensor?

 

Agree with Joz i have just replaced my lamba for the same reasons overfuelling running rich now running perfect i advise get a genuine lamba.

 

how much are the lamba sensor mate cheers

 

does any one knw how much these lambda sensor are

 

about £120 if i remember correctly

 

I bought a brand new OEM Subaru one from Zen about 20mths ago to help get it through MOT. IIRC, I think it was around £165+VAT.

The upside is that the OEM one works beautifully and will last years....

 

Wel just had cat and lamba done and stool will not pass an emissions test need to get a garage that will do me a mot wid diffrent car 4 emission 4 test in Leeds any help

 

I take it it failed on CO2 content on the 2nd fast idle test?

* Coilpacks next. Could be one... all 4... or any number in between, breaking down and causing inaudible misfires - thus running engine rich when it happens.

* Then MAF sensor (but unlikely).
