Engine Cut-out - Mitsubishi Lancer

Hi, just bought a 2nd hand '96 Lancer (not sure are they called something different in the US, I'm in Ireland).

When the engine is cold it has a tendancy to cut out until the engine heats up a bit. I know that hooking it up to the computer might easily be able to find out what is the prob but it's fairly expensive over here.

Someone with experience was telling me that there's an adjustment screw somewhere round the air flow meter that might solve the problem. But I can't find it!! Can anyone advise or tell my where i might find a pic of the engine with this screw marked??

Thanks, John McG
