Re: 3 lambda sensors??
It depends on the problem with the lambda - if it is completely bust then yes you will get a warning but if it's sluggish then you may get an entirely different fault code.
I don't want to sound clever after the event but I don't like the idea of always replacing the most expensive parts before looking at the cheaper options first.
Did the garage look for fault codes first and did they talk over the possibilities? Far too often they seem to want to start changing MAFs and lambdas and when they don't solve the problem they make excuses - they should be able to stand over their work and if in doubt should be able to substitute parts without you paying for them if they don't fix the problem......after all you are paying them to fix the car not to charge you for unnecessary work....rant over.
A worn throttle position sensor can cause 'hesitation' or 'dull' zones when accelerating so maybe get that tested.
