Increased plug gap improves idle
After a year a screwing about trying to fix a rough idle when cold (plugs, leads etc etc), I decided based on an a real old thread about another issue, to increase the plug gap from the recommended 1.1mm to 1.3mm. The car now idles perfectly. Maybe the extractors, PULP and a few degrees extra advanced timing made it want more gap to burn better. *shrug*
