Hi,
This little car won't pass the MOT because of high CO,
The car is running Rich all the time, the lambda is reading rich and rich it stays, if i disconnect a vacuum pipe it goes to lean, so i assume the lambda is ok.
I've checked EGR, Coolant temp sensor, injector, fuel pressure, and all of that seens to be ok,
