Just curious what the worst emission test results people have had?
Ive just put a VR4 (not mine) in for an MOT and surprise surprise its failed on emissions. Not in a marginal way either, we're talking about 9% CO at fast idle!
Not sure whats going on with it, at low idle its not too bad, just a bit over 0.4% but HC's are fine and obviously lambda is low (as it would be due to the richness).
Now, using evoscan, the water temp is fine, tps is fine and lambda sensor is working.
So anyone had anything similar?
