Hey people

my s2 escort rs turbo has an idle fault.
i am at my wits end with this fault, basically when you start the car first thing when the cold
start is on it ticks over perfect when that comes off it keeps cutting out unless you keep the revs
up for a few minutes then it heats up it ticks over fine but has a bad missfire.... drives fine though.

so far i have changed
dizzy, dzzy cap, rotor arm, fuel filter, metering unit, spark plugs, leads, air filter.

oh and this is just started the past couple of weeks.

any ideas ....
