Monitor your Idle Control Valve voltage. I suspect the valve is gummed up and not responding well until engine heat loosens the internal lubricant. If, however, voltage to the valve is low or null during warmup, the problem is elsewhere. If it is the valve, clean it or replace it.

The voltage changes depenging on engine temperature and the idle rmp seems constant... if I, however, remove the power from the engine (at cold temperature) it lowers the rpm and at warm engine temperature the rpm increases.... So it SEEMS to work fine, but you never know, right?? ;-) ... But you guys think that cleaning the idle contorl valve will fix this? That might be a good idea... I will try it. What kind of lubricant do you need to put in there after cleaning???
