2005 Peugeot 206 running rough/lacks power

Car: Peugeot 206
Year: 2005
Variant: gti 137bhp model
Categories: Running Rough, Starting & Power Loss
When I start the car it idles lumpy. When you drive the car I have to put the accelerator pedal to the floor to get it to go. It lacks power in every gear and lerches when you are at a constant speed. The engine management light keeps coming on stating an ANTIPOLLUTION FAULT. I have taken the car to a main dealer and they plugged the diag machine on and said that the lamba sensor was faulty. I had this changed at alot of exspense, but has not corrected the fault. Can anyone help me

may be plugs/coil fault but these do suffer with hydraulic lifter faults.check oil level also check coolant thermistor and check connector to make sure it is not wet.

Forgot to mention, I have also had a new camshaft sensor fitted, but has made no difference.
