oxygen sensor?

Have checked and compared pt numbers and they do use the same sensor .
Lambda is constantly changing the mixture of air/fuel and of not reading correctly / working will give you a rough idle.  But more than likely its a dirty inlet / throttle as when a lambda sensor fails it will run a factory safe mode to the lambda to prevent over fueling and burning the cat out

wicked. but it came up as a fault code when plugged in so i imagine its still worth changing. i was planning on cleanign the throttle body anyways to see if that helps

Oh yea don't get me wrong if there is a fault code for it then its had it for sure . but what i was getting at is they run a safe mode when they fail and run a certian mix to prevent damage to the cat so you may find the idle issue is unrelated or may be related with a mk3 nothing is certian and they certianly love new parts espicaly coil packs .

think i just saw your car parked up in the greys road car park earlier about 10.30 ? looks nice if it was yours ! ,
