Hi all!! Can someone please help. I have a hunting issue on idle. At 1st it would hunt between 1 and 2 thousand RPM. I have done a flash test and the code come up was (no known faults) so I unplugged the idle control valve on the right hand side of the inlet manifold at the back. The engine ran the same. So I took the idle control valve off and it seemed a bit gunky so I gave it a good clean put it back together and put it back on. The car now sits at 1500RPM when warm and doesn't hunt. I've checked all vacuum hoses and they are all ok. So does this mean the idle control valve is faulty? And can someone point me in the right direction to a parts dealer or shall I just use nissan?
