hello again
following up my previous post (Pattern Parts) it seems replacing the front pipe on my punto has uncovered a whole load of other problems.
After the 2nd cat and 3rd front pipe being fitted today, it was still making the same "whistling" noise when accelerating under load. The fitter guy took it over the road for an emissions test and seems it failed badly with high CO readings.
So...faulty Lambda Sensor???
I'll be jiggered if i can find one on my exhaust system.
Please, someone help me before i set fire to the thing.
Thankyou
Dan
