I have a 1.6sx liberty Tipo with the current problem as in my previous thread. I am going the change the Lambda sensor but a few people have told me that the sort of problem i'm getting could be the MAF or MAP sensor as its works out the injector operation between the readings of the two sensors. I have looked in various books but can not see a sensor called this. Is this true or am I being told a load of B****ks. Please can someone put me straight about the issue (If it has where is it?).
