Hi guy

whenever i start my 1994 WRX up from cold

for the first 10 second it runs fine on choke

then after this is starts to missfire on idle, also if you try to rev it a little it does the same

as soon as the engine is hot it runs fine though

also when its missfiring there is a "snicking" noise coming from the drivers side under the bonnet

any ideas??
