Hi my Punto speedgear 2000 is fitted with new cat and new lambda but it does not go closed loop normally and stuck around 0.475 volts with open loop. But when I manually grounded the ground wire from wiring loom it goes closed loop and can see mostly the fluctuations above 0.450 volts. Please advise.
