g60 lack of power confirmation please

[sim0n_parker 0]

right ive searched through the search's and i think ive narrowed i down,

 

basicly every now and again ill go to put my foot down in my G60 and it lacks power. you really have to wind it up and then all of a sudden its back in and boosts really well.

ive checkd all my boost hoses etc and they are all tight and nice and secure. at this moment in time i my old lambda sensor had broken wires (OE part) and the previous owner cut the engine loom plug of and used crimps, so at the moment it has got an after market lambda sensor on it with crimpd terminals that sit into after market sensor;s plug. (if you know what i mean?)

 

i have read up and found a huge amount of people on here have had trouble with aftermarket sensors, does it sound like this lil things at fault? anyway to test?

thanks

simon
