hey all..
My GTR's idel is all over the place..
when its cold it seems to stay around 1200rpm..
then when i start driving and stop at lights etc the idel creeps up to 2000rpm.
it will then slowly drop down to around 1000rpm and bounce up to 1400rpm etc.
the car is also running very rich..
i have replaced the afms, and the O2 sensors with no success..
any ideas?
