when I started my FD this morning it had a high idle at around 1700RPMs it then started to bounce from 1700-1500RPMs I am guessing it may be the O2 sensor but I really have no idea any help or suggestions would be great PLEASE HELP!

 

also look into tps ..

 

i have this problem changed lamda this weekend - no different!

mine is also bit flat on 2nd turbo if you plant it,

thinking my injectors might be going a bit iffy

booked in at a specialist on the 14th of this month

regards
will

 

O2 sensor wouldn't affect this because the car hasn't warmed up and reached closed loop mode yet. The computer isn't using the o2 sensor as a signal input yet.

 

vaccum leak might be possible.

 

check map sensor vac line.

 

mine fixed now, faulty idel control valve, located under/behind pipe entering into inlet manifold
