Hi there,
My Bravo 1.2 16v developed a strange issue. I failed last MOT due to high CO value and fuel residue.
My mechanic replaced faulty cat and lambda sensor but values are still on high side. Strange enough engine runs fine and fuel consumption is normal.
It looks like ECU is ignoring lambda sensor, engine runs the same with lambda disconnected. Dash control light goes and remains off after engine start.
Any ideas?
