car is misfiring when I put my foot down and is running really rich.
One Lamda is unresponsive but as Lambda control is turned off on the ECU could this be the problem, every thing else is reading perfect?
Injectors, coils packs, leads every thing else is new so should be OK.
Coolant temp sensor? Will cause rich mixture if stuck at cold.One Lamda is unresponsive but as Lambda control is turned off on the ECU could this be the problem, every thing else is reading perfect?

A misfire results in unburnt gases which the lambda detects and more oxygen from the misfire will cause the ECU to increase fuelling.
By revving and lifting off can you get any movement on the unresponsive lambda?
Guess it will be leads as the next thing to change, tried the air tem sensor first as that was causing a fault to be logged with the ECU, it is better but not quite right since. I know the leads are suseptable to heat and believe me she did get hot under the bonnet when on the rolling road being mapped so it could well be something that simple:-)
Thanks for the advice chaps, your are as ever very helpfull and much appreciated, got to love the Cerb forum.
