Advice please, 96 GLANZA V  In mostly cold starts it misfires for about 5 seconds before running on all cylinders and never misfires again. Also when I've just parked up after driving and go to start it again it takes a little longer than usual to fire up.  I was thinking coolant temp sensor maybe?  All the ignition system is brand new, plugs, dizzy, rotor arm, leads.  Any help would be appreciated
