Toyato Carina E 1.6 1997 Lean Burn - CO reading fault 2.5 at high revs # Archived Message

I have this problem with high and low idle, CO readings of 2.50 high and 0.80 low I had air leeks on injector seals and replaced same to fix but did not help emissions. Live readings on coolant sensor 85 to 90 degrees OK and voltage OK hot pulse on injectors 2.8 mil seconds 02 sensor reads at idle 0.4 with very little wave form and at high test 28 to 3000 RPM it goes to 0.8 with very small wave form, fuel pressure ok at 2.5 to 2.9 map sensor is scoped OK I have fitted new oxygen sensor (Lean burn 0E sensor) readings still the same car drives and runs sweet have disconnected battery to re boot with no change I presume I am right is testing this type of sensor on the blue wire. I would be grateful for any help regards Owen
