cold start problems what to do ?

Hi guys, im familiar with alot of aspects of the scoobie but never had this fault.
got a subaru impreza wrx 1994 import and its just a total bitch to get started when cold,

once started i need to hold the revs manually on or above 1500rpm to get some heat in the engine, only after holding the revs for a while will it idle (at 800-900 rpm)

when its starting from cold and the revs drop under 1500rpm it really sounds like its firing on 2 or 3 cylinders

also when starting it like this its really hard to rev the engine (until its above 1500rpm) it seems the less accelerator pedal i give it to rev it the easier it revs , if i plant my foot down it just cuts out.

Re: cold start problems what to do ?

sorry i should have mentioned a bit back ground info on the car.

The previous owner says he changed the temp sensor and it didnt work (i took his word for it but he seemed genuine)

but here are a few other things which may be relevent.

the car had the head gaskets done, valves changed etc (reciept present for the work carried out)

however the radiator fan stays constantly on and doesnt go off possible link between the faults ? (has been disconnected while its cold and was just gonna put on a flip switch if it worked out costly to repair.
