Fix High Emissions

[greddyfreddy]

I failed at emissions today. The figures were throught the roof. I then removed the cables from the battery and pushed the lambda plug into its socket. It seemed a bit out. I also replaced the plugs with Brpc6es. (not 100% sure hey vwere called exaclty that)

I then checked the readings again. and came up with ths result. See picture.

These values are way lower then at the first reading. I then tested to unplug the lamda from the exhaust manifold. And then the CO % dropped to 1.0 and lambda increased to 0.97. Thats really close to what i need if you compare it what i started with. The CO has to be below 0.5 i think. Any idea what is going on? The lambda must be broken, right? More tips on how to get the CO down to pass emissions?? I need to pass it tomorrow or else i have to wait a month. :down:

thanks

Put on a new Cat! The one on now might have died

I got it sorted. I fixed all the boost leaks and i bought a new lambda sensor. that fixed the lambda readings.

I then took the cat down, and it was just small bits in there. So after that it flew through MOT. :thumbs:
