Hi , i ve got a problem, which is driving me mad

my car starts fine when its cold ie over night , and drives well and idle s well from cold .on satrting it revs to above 850 rpm and drops down to 500 rpm once warm

It also , starts well at normal operarting temp and will idle ok here too

but if left for 2 , 3 or 4 hours it will start but will not idle ,

It can be caught with the throttle , put put into drive , and will normally die unless over 1000rpm on throttle , drive stright off 2 to 4 mins and its perfect idleing , i've change the blue temp senor and measured the resistance before starting =16000 ohm , once warm 300 ohm , and before stsrting after 3 hrs ( measues 1000 ohms . i ve also swopped the idle control valve for another one thats been cleaned out ? , i ve checked thw hoses for air leaks , new bellows too , and measured the blue tenp sensor voltage 4.3 v with ignition on , i get 4.8 at the brown sensor to earth ? what else is there to do ??
any idles :cry:
